13 May 2021 12:00 (UTC+02:00 Europe/Paris): After discussion with Microsoft spam service, emails sent by the vote machine to hotmail.com, msn.com, live.com, windowslive.com and outlook.com addresses and country variations will no longer be blocked by Microsoft spam filter. Use the Help tab to resend blocked emails of currently running votes. At the previsualization step, a strong message still warns the vote creator of Microsoft spam policy.
11 May 2021 21:00 (UTC+02:00 Europe/Paris): Microsoft email addresses hotmail.com, outlook.com, msn.com, live.com, windowslive.com and country variations have been blocked by Microsoft since May 5th 2021, despite SPF, DKIM and DMARC compliance. The issue is being discussed with Microsoft. Please do not create votes for now using these addresses, until the problem is solved, since email delivery will be blocked by this company. Warning at the previsualization step.
30 Sep 2020 20:00-23:59 (UTC+02:00 Europe/Paris): At some point within the 4 hours long period of time, the vote machine will be unavailable for approximatevely 20 minutes due to a maintenance on the server host infrastructure (more informations). Sorry for the inconvenience, independent of our will.
30 May 2020 22:00 (UTC+02:00 Europe/Paris): The vote machine security has been updated to the most recent cryptographic protocols. As a consequence, all vote creation bookmarks - recalling previous vote data to create another vote - are nullified and must be created again. Sorry for this inconvenience forced by security enhancement. ADoodle.org SSL certificates are now rated A+ by Qualys. SSL Labs at https://www.ssllabs.com/ssltest/analyze.html?d=adoodle.org.
18 April 2020: The vote machine has undergone transcient overload around 20:00. It has been disconnected for between one and two hours, and then reconnected. Sorry for the impact on running votes. The origin of the overload has been identified (vote file locking mechanism) and solved. Everything is back to normal.
17 March 2020: The following issue has no link with Corona-virus 2019 proliferation. Firefox browser in its new version 74 apparently warns the user of an outdated cryptographic protol TLS1.0/1.1 used by the vote machine. The transmission to and from the vote machine is still encrypted but with an outdated algorithm that is not ultra-strong attack graded. If this is a problem for you, be advised to use another browser, or temporaily accept the lower graded protocol. Until update is in place, note that highly skilled computer pirates or military or gouvernment could potentially break the encryption for your vote. The vote machine will be updated as soon as possible. Details at https://globalsign.ssllabs.com/analyze.html?d=adoodle.org.

Create a survey or vote
It is a good practice to have a look - first - at the recommendations to vote creators in the Help tab.
Then please choose on the left the language and time zone (sorted by continent, then city) of the interface and of the sent emails. The emails always contain an English version.
Please use only the buttons on this web page, not the Back and Forward buttons of your browser, which functions have been altered for security reasons.
1. General information
This will be the subject of the sent emails. Choose a distinctive title.
For the information to the participants.
The voters will select an answer corresponding to this question. If you need to display a new line, type <br>.
To tune the question form, you may also use a limited set of HTML tags: <b>, <strong>, <i>, <em>, <mark>, <small>, <del>, <ins>, <sub>, <sup>, <h1> to <h6>, <p>, <ol>, <ul>, <li> and corresponding closing tags </b>, </strong> etc.
2. List of choices
The voter can only choose one of the proposed choices.
→ If you want to allow zero or multiple choices with check boxes
Please give a list of emails (one for each line or in comma separated form or else).
The voter will receive an email containing a unique personal vote ticket and two links to vote and to display the results of the vote. Naturally a voter can only vote once. All the links with email address are erased from the vote machine memory at first use, hence the anonymity.
NB: Check carefully the emails. All emails must exist and be valid and must not block emails from ADoodle.org. Do not use group email addresses.
An excellent practice, with this list, is for you to send an announcement message to the participants (using your own email account), before creating this vote. It will help you detect defective addresses. Once the vote created, note that the emails addresses can no longer be changed. See 'Help' tab about vote creators.
Weighted voters - Option (click to open/close)
You may define weights for the voters by indicating a weight after each email address. Do not worry about the format, simply put a weight number (integer or floating point value) after the email. The weights will be extracted whether they are alone or in parenthesis or brackets or else.
For instance if you enter:
it means that there are three voters with vote weights of 2, 1.5 and 1 respectively. In this case the total weight is 2+1.5+1 = 4.5.
Anonymity considerations. If you choose to define weighted voters, the full anonymous character of the vote cannot be strictly guaranteed. See Help tab. In pratice, to increase anonymity, try to maximize the number of identical weights among the voters and to maximize integer ratio between the weights (e.g. weights such as 1, 2 and 3 or 0.25, 0.5, 0.75 etc).
Please give a list of emails.The observers will receive an email containing a link to display the results of the survey. An observer does not vote. All the links with email adress are erased from the vote machine memory at first use, hence the anonymity.
If you create the vote and do not vote, then put your email here to follow the results.
NB: All emails must exist and be valid and must not block emails from ADoodle.org. You may use group email addresses. See 'Help' tab about vote creators.
No dates are defined. Voting and observing the results will be possible at all times.
If you want to limit vote duration and prevent disclosing the results during the vote period of time (recommended), please add date limits:
Please review carrefully the other parameters of your vote.
A check mark means that the option is active, otherwise the option will not be applied.
If you have got a code from support, please enter it here.
6. Preview the data
By clicking on the following Previsualize button, the input data will be checked and the vote data will be previsualized.
Vote for your choice
To vote you will receive an email with the proper link.
You can also enter your vote identifier and personal vote ticket here:
To see the results of a vote you will receive an email with the proper link.
You can also copy and paste the vote identifier here:
Here is a demonstration of the vote creation steps.
1. Define the vote ↑ Menu
The first step is defining the parameters of the survey/vote. Do not worry, if you forget something ADoodle.org will tell you what is needed when you go to the previsualization step.
Your main effort should be the email list, whatever its format. It is your responsibility, considering the participants, to provide a list of valid emails. Otherwise some participants may not receive the vote email. A good practice is first to invite the participants to a test survey.
2. Check the vote ↑ Menu
The previsualization step checks that the vote parameters are correct. This step also helps you previsualize and check what kind of email will be received by the participants.
You can go back at any moment by pressing the "Previous step" button at the bottom of the page. Do not use the back button of your browser because the memory cache of the browser is deactivated for security reasons.
3. Create the vote ↑ Menu
You may now confirm the vote creation. Once you press OK you cannot go back. The vote will be created and available at all times to the participants only. Note that a vote cannot be deleted.
After the emails have been sent, you can see a confirmation that all the emails have been correctly emitted.
It is important at this moment to close the page or your browser. If you happen to reload this page somehow, then a second identical vote will be created. You do not want that.
Here is typically what you will see when clicking on the vote link:
Once you have voted, the page confirms your vote and propose you to go to the result page.
5. Observe the results ↑ Menu
Here is typically what you will see when clicking on the observer link, to observe the results of the survey/vote. Note that a textual (detailed) description is given for a clear analysis of the results.
6. Conclusion ↑ Menu
As you see, ADoodle.org is fast and simple. Here are final recommendations:
- CHECK carefully your email lists.
- WARN the participants that they should expect an email from email@example.com. Suggest to check the spam folder. Emails from ADoodle.org are not spam.
- Consider creating a TEST vote before the "real" one.
Note that some other useful options are available like adding date limits, or defining weighted votes if really necessary.
Have a good anonymous vote.
Here are Frequently Asked Questions (FAQ). The definitions of the terms voter, observer, creator etc. are in the 'Help' tab.
1. What is ADoodle.org? ↑ Menu
ADoodle.org is a website to organize, in a very simple way, an anonymous survey or vote.
2. What are the founding principles? ↑ Menu
ADoodle.org is based on simplicity, fairness through transparency, equality through full symmetry between the voters and the anonymous character of the cast vote and participation.
3. What is anonymous? ↑ Menu
- The cast vote is anonymous, not the list of potential voters and observers.
- The vote is even doubly anonymous. No one knows who has voted.* No one knows what a voter has voted.* The reason is that the vote machine only recognizes random personal vote tickets.
- Also internally, the vote machine does not know who has voted.* The reason is that the temporary relation between the personal vote ticket and the email is erased at the first connection of the voter, before the voter has even voted or not.
* Concerning anonymity please keep in mind 2 very general facts that are not specific to ADoodle.org. 1) Your active participation anonymity is lost if all the voters vote (in this case all the participant will know that you have voted) or if no one votes (all the participants will know that you have not voted). 2) Your vote anonymity is also lost if all the voters vote and vote for the same choice.
4. How do I know that the vote is anonymous? ↑ Menu
- Each voter receives an email with a personal vote ticket. The personal vote ticket is a random number that does not contain any information on the email.
- The server itself erases the relation between the email and the personal vote ticket as soon as a voter connexion occurs after a vote has started. The email lists are also completely erased after the end of the vote.
- With this procedure one can vote anonymously, from the vote creator side, from the other participant sides, even from the vote machine side.
5. What is public? ↑ Menu
- There is no public information about a created survey. Only the voters and the observers receive information about the vote they belong to. So the question is actually: what information is available within the participant group?
6. What information is shared among the participants? ↑ Menu
- All the participants share the same information about a created survey: voter and observer lists, title, question, choices, dates etc.
- The vote creator does not have more or less information than any other participants. S/He is simply the person who creates the survey. The vote creator does not have special powers.
- Since the email list of voters is received by all the participants, each involved participant can control the conformity of the list with what has been announced by or agreed with the vote creator.
- The list of observers is also transmitted to all the participants. The observers are the group of people who do not vote but get the link to the result page as well.
7. What is stored? ↑ Menu
- The voting tickets (random numbers) are stored on permanent files.
- Emails addresses are only temporarily and partially stored, elsewhere, until the end of the vote or the first connection of the voter. The relation between the personal vote ticket and the voter is erased as soon as possible, at the first connection to the website, before any vote operation from the voter. All emails whatsoever are completely deleted after the vote end.
- An observer typical email, such as the one sent to the observer(s), is sent to the webmaster for statistical purposes and minimum support, as well as with connections to the website.
- ADoodle.org data including emails are used for the sole purpose of the election management and nothing else. ADoodle.org does not transmit nor sell any data to third parties, either commercial or non-commercial. Notably ADoodle.org does not transmit the vote files containing vote input parameters, including temporarily email addresses and output results.
8. What is not stored? ↑ Menu
- As soon as a voter connects to the website the email relation with the random ticket is first erased. After the end of the vote, all the remaining email lists whatsoever are deleted from the vote files. As a result the email list ends to be only available in the sent emails and known from the addressees, and not stored on the server.
- One could argue that the list of emails may be kept stored in some uncontrolled system disk or memory cache or system log file but 1) this is out of any user reach anyway 2) in any case the relation between the emails and the personal vote tickets is deleted.
9. How does it work? ↑ Menu
- Personal vote tickets are created randomly from a seed provided by date and time measured down the microsecond when the creator creates the vote. Sophisticated pseudo-random generator is used, cryptographically graded. It is therefore virtually impossible to predict the value of this key and the values of the unique tickets sent to the voters. The machine has no knowledge of relation between a voter email and a personal vote ticket when the vote occurs. The machine no longer knows what are the email origin of the vote anonymous tickets.
- The personal vote ticket is basically a unique large binary random number like 2c9586f8ac66be373ef6e5041e965224 in hexadecimal format. This number is chosen so that it cannot be easily guessed by anyone, even a computer (see strength limits and security considerations below).
- Beware: if one person appears in the created voter list twice with two different emails, then this unique physical person will be allowed to vote twice. To counterstrike that, the email list is transmitted to every participant with their voting tickets. So everyone can check that the list is ok. The person creating the vote must take care to provide only one email for each participating real person. Note that the vote machine checks email lists for obvious duplications and wrong email addresses but only in their Domain Name Server after the @ sign.
10. Security considerations ↑ Menu
How are transmission secured?
||The web site uses strong cryptographic secured connexions (SSL certificates and https://... links) ensuring the condifential transmission of your vote from your internet browser to the vote machine. ADoodle.org SSL certificates are rated A+ by Qualys. SSL Labs.
How strong is the anonymous character of the my cast vote?
When you cast your vote, it goes through an encrypted secured channel (technically https://...) and no-one in between can see what your vote is. Since the vote machine has no knowledge of the voter identity at vote time and after, and only counts cast votes, your cast choice and choice related identity are rather well protected.
How strong is the anonymous character of my participation to a vote?
Your participation now is as anonymously strong as the security on email traffic is. If someone gets access to your email, s/he could see that your are involved in a specific survey. Using your personal vote ticket, s/he could see either that you have voted or that you have not voted (but s/he could not tell what you have voted). Or s/he could vote instead of you using your vote random ticket. In this case if you try to vote after the "spy" did, you will not be permitted to do so and therefore you will realize that something has gone wrong.
Your internet browser may keep some vote or result links in its browsing history. However these links do not contain any identity information. One can vote only once. In the vote machine, the relation with the email is deleted at first connection after the vote start date and all the emails and remaining relations deleted after the end date.
So if you think that reasonably no one will look at your emails, then your can participate with good trust.
When should I not use the vote mechanism provided by ADoodle.org?
If you think that someone may listen to your email (unsecured) traffic, such as a computer-skilled colleague or the computer administrator of your network, AND may be ill-intentioned then you should not use this website. If you think some unwanted person is liable to observe your email traffic, do not use this vote mechanism. This person could vote instead of you. If you do not trust the webmaster (see contact at the end), do not use this website.
So in conclusion?
This website has been made so that small more or less formal organisations (such as a group of well-intentioned co-workers, scientists in the case of the webmaster, or friends) can organise quickly a convenient electronic vote. The website gives vote action anonymity (not voter email address anonymity!) to probe voters' overall opinions without going through an "every-one-knows" or "I know nothing" doodle procedure. The vote mechanism is both simple and anonymous.
Your vote will always be cast anonymously. If you think that reasonably no one will look at your emails, then your can participate with good trust.
11. Robustness ↑ Menu
- The vote creator is informed of the success of the vote creation and of each email emission. This is controlled by the vote creation mechanism.
- If a technical problem occurs during email emission (e.g. overload), the vote is immediately invalidated. No one will be able to vote. The participant will be informed, directly on the result page, that the vote is not available.
- If a participant does not receive the email, it can be re-sent only if the personal vote ticket has never been used to connect to vote machine and only before the end of the vote.
12. Limitations ↑ Menu
- Emails are digitally signed. Email emission is SPF, DKIM and DMARC compliant.
- Email emission is tested for success (or failure). Email transmission, is based on the robustness of email communications through the internet (which is pretty good). However if a participant is behind a server/firewall that purposely blocks ADoodle.org emails, the participant will not see that a vote has been created. Because the distant email servers do not always tell that they block emails or not, there is no definite way of knowing that the email did not arrive at destination. Even if they do tell, ADoodle.org does not detect bounce emails. It is therefore a good practice, for the vote creator, to test and to inform the participants that they should expect an email from: firstname.lastname@example.org and that they should react if they do not receive it. The participant can have the email resent in the Help tab. These emails are not spam.

14. Plan for future versions ↑ Menu
In a future version, ADoodle.org will implement a mechanism to detect bounce or incorrect or unresponsive email addresses.
Also compliance with accessibility (see e.g. http://wave.webaim.org) will be improved.
15. What does ADoodle mean? ↑ Menu
ADoodle is simply the "Doodle" word with a first capital letter meaning Anonymous. ADoodle.org lets you set up a vote or poll or survey which is anonymous for the participants. doodle.com is a famous website used to organize meetings or to make a choice. In the latter case, the participants must expose their choice to everybody else or let one person control the result page. ADoodle.org let you organize an anonymous vote among your colleagues or friends with maximum transparency, full symmetry between the participants, and reasonable anonymity in the vote and participation in the vote.
16. How do I contact the author of ADoodle.org? ↑ Menu
Questions, opinions, suggestions, criticisms or encouragements are much welcomed. The webmaster can be contacted at adoodle[at]sebsauvage.com. Please replace [at] by the @ character. My job is scientific researcher in Physics in a laboratory which requires some anonymous probing of opinions. Hence this website.
If you do not find answers to your problem here, please contact the assistance: email at the bottom of the page.

How does it work?
The best way to understand how ADoodle.org works is to see it in action. For a start try to create a vote using your own email address in the voter list, or possibly several of your own addresses.
I have not received the email. What can I do?
Please first have a look in your spam folder and at the recommendations to the participants below.
If you have not received the voter/observer email, or if you have lost it, or deleted it, please below ask the vote machine to attempt to re-send it. Re-sending is possible as long as the email has not be used to connect to the vote page and as long as the vote has not ended and only for surveys created after 1st July 2016.
NB: Whatever the entered email, this process will not disclose any information. An information summary email is always sent when clicking 'Re-send'.
I do not remember if I have already voted or not. How can I check that?
In the received email, click on the vote link to connect to the vote page. The vote machine will tell you if your personal vote ticket has already been used to vote or not.
How to unlink immediately my email address from the vote ticket?
In the received vote email, simply click on the vote link (the first link) to connect to the vote page. That's it.
Indeed, when the vote page is loaded, the vote machine will immediately erase your email address relation to the vote ticket. Please note that this relation has been kept temporarily only for re-send purposes. Re-sending the vote ticket is useful e.g. when the vote email is lost before being used. Beware, after clicking, keep carefully the vote email if you want to vote later, because resending the vote ticket will no longer be possible (definitely anonymous).

- Check carefully your email lists.
There is no way to correct the email list after emails have been sent. ADoodle.org does not detect bounce emails. Suggestion: send an email to this list to check its validity, using your own email account.
- Warn the participants that they should expect an email from email@example.com.
- Add ADoodle.org as an accepted domain in the spam filters, before creating the survey.
- Suggest to check the spam folder. Emails from ADoodle.org are not spam.
ADoodle.org cannot control the spam policy of the participants. Warning the participants will help you check that all email addresses are correct.
- Consider creating first a test vote before the "real" one.
If a participant server blocks ADoodle.org emails on purpose, ADoodle.org cannot do anything about it. ADoodle.org cares about email emission but cannot check email reception (the emails end up to be deleted on the ADoodle.org server).
3. Recommendations to the participants ↑ Menu
If you do not receive ADoodle.org emails, configure and look into your spam folder.
- Configure your spamfilter not to catch ADoodle.org emails. Emails will come from adoodle.org domain, more specifically from firstname.lastname@example.org address.
- If you do not receive ADoodle.org emails, check your spam folders in your email application and at your email server. When not properly configured, it may happen that spamfilters wrongly flag ADoodle.org emails as spam. Look for the email there.
- If your emails are forwarded by your email-account, check that forwarding does not block e-mails from ADoodle.org.
Please note that re-sending an email is possible (see the top this tab) as long as the email has not be used to connect to the vote page and as long as the vote has not ended.

5. Vote mechanism ↑ Menu
- Someone, called the creator, creates the vote or survey by providing a title, his name (or pseudo), a question (or subject) and a list of possible choices.
S/He also provides a list of voters and possibly a list of observers (who do not vote).
The set of voters and observers are referred to as the participants.
- All the participants share exactly the same information. ADoodle.org is based on fairness and equality. Everyone involved in the vote knows who are all the voter emails, who are the non-voting observer emails and can see the results of the survey. The vote creator - if s/he has included her/his email address in the list of voters or observers - does not know more or less than any other person involved in the survey.
- When creating the vote, a vote email is sent to each voter to vote and look at the results. An email is sent to each observer to look at the results, but not to vote (see figure).
- With the vote email to the voters comes two links. The first link enables to vote and should be kept secret, unless one wants to transfer its voting ability to someone else. The second link corresponds to the page of results. A priori it should not be distributed, unless the participant wants to expose the results to some other people, possibly once the vote period has ended.
- One voter (i.e. one email address, i.e. technically one vote ticket) can vote only once .
- The vote machine has no knowledge of the physical identity of the voters. In particular the server, at voting time, has no knowledge of the email address of the voter.
- The vote machine keeps track of the number of voters, number of voters attentive to the vote and counts the various vote choices. A voter is said to be attentive to the vote if s/he (more precicely her/his vote ticket) has connected to the vote page, by clicking on the link received by email, but did not vote.
- The vote mechanism is the same for all voters. Note however that each voter can vote only once and can no longer vote after having voted. The voter can have knowledge of the results of the vote during the vote, if allowed by the vote creator, and at any time after the vote period of time.
- A voter can transfer his voting ability to any other person by transmitting the email s/he has received for the survey.
- The vote creator does not have special "powers" except the initial one to create a survey.
6. Weighted votes ↑ Menu
- First, in an usual vote one can say that the weight of each vote or voters is 1, because 1 person equals 1 vote. The total weight of the votes is the number of voters (or total number of cast votes depending on how the results are presented).
- In a vote with weighted votes, the vote creator gives an arbitrary weight to the vote of each voter (e.g. 2 or 0.1 or 10 etc). The results are constructed from the relative weight of each choice with respect to the total vote weight, see the figure above.
- Weighted votes are an easy way to probe the opinion of represented groups of people. Each group proposes one representative voter. You want each voter to have a weight corresponding to his/her group size. In this case weighted votes is a straightforward solution to get accurate representativity.
- Weighted votes may be useful in some cases such as in "Grands Électeurs" systems, but should be regarded as bad practice here because full anonymity cannot be guaranteed.
- If you choose to define weighted voters, beware the anonymous character of the vote may not be guaranteed. For instance if all the voters have a weight of 1 except one voter who has a weight of one million, it is obvious in this extreme case to see if the latter voter has voted and what s/he has voted. In practice anonymity can be good without being strict as in a non-weighted vote. Note that the participants will be informed of the weights of all the voters. In the case of a weighted vote, the participants will be informed that the anonymity cannot be guaranteed.
- If you set up weighted voters, try to maximize the number of identical weights and to maximize integer ratios between the weights. That will increase partial anonymity.
