Your subscription month (or year, depending on your subscription) starts on the day you subscribe. For example, a LimeSurvey Professional BASIC package bought on April, 23rd will be automatically renewed on the 23rd of May.
The minimum duration for a subscription is the base subscription period of the particular plan. You can cancel it online yourself at any time to the end of the current subscription period.
If you cancel it in writing (by email or letter) you need to notify us at least one week before the end of the cancellation period.
If you cancel your subscription, you will continue to have access to all features of your plan for the time period you already paid (this is the same for LimeSurvey Premium and LimeSurvey Professional). If you are using LimeSurvey Professional and the subscription has expired, you will fall back to the Free package. You will still be able to access all collected responses and use all features of the Free version.
Yes. Your subscription will fall back to the FREE plan after the paid period is over (assumg that you cancelled it). Please note that some features (such as domain aliasing) are only available with a paid subscription.
Yes. At the end of each subscription period your response volume is reset.
For example, the BASIC package will set your response volume to 1000 at the end of your month period.
No. Only after the paid subscription period has ended will your subscription fall back to the FREE package, which will set your account to 25 responses.
We are sorry, but the prepaid packages are not available anymore and will also not return in the future.
LimeSurvey is free open source software and is therefore created by and available to anybody.
We would like to contribute to that by granting discounts to all of those with a great cause and a small wallet.
Discounts are available to:
To apply for one of our discounts, please get in touch with us using our support tracker or send an email to firstname.lastname@example.org.
Charitable organisations should provide a proof of charitable character, or a description of their non-profit work.
Universities and schools should provide a certificate of their institute (website, flyer or the like.).
Students should provide a scanned copy (both sides) of their valid student ID card.
We reserve the right to reject any discount without the need to disclose any reasons.
We're sorry, but we cannot give discounts for purchases in the past.
Yes, LimeSurvey software is free open source - everyone can use, modify and distribute it for commercial, private and educational
purposes under the GPL license v3
(exception: the name and logo LimeSurvey is trademarked,
so please don't advertise commercial services using the LimeSurvey brand.)
The development of LimeSurvey
has moved to a professional level, so we need funding to pay our developers.
That is why we now
offer a premium package for LimeSurvey.
At first, this Premium package will include ComfortUpdate
only, which can be used to conveniently update LimeSurvey from within the application. If you don't want
to use the ComfortUpdate function, you can still update to the latest version manually.
At a later
point, we will add more functions to the Premium package, so stay tuned!
LimeSurvey is under GPL so every feature in LimeSurvey will always be open to the general public.
However, there are feature components of the software like template editing, advanced survey export and so on that may get paid extras in the future.
A response is counted if a participant completes your survey once, regardless of how many questions or question groups your survey contains.
In a more detailed description...
- A survey is taken and completed => 1 response
- A survey is taken and only half completed => 0.5 response
- A dataset is manually added by an administrator => 1 response
- A partially completed survey is marked as finished by an administrator => 0.5 response
There are no locked features in LimeSurvey except for the response and upload limit. Some additional services (like domain aliasing) are only available with the paid subscription plans.
At first, we will send you a warning by email that your response volume is getting low - you can set this warning limit in your account settings after registering.
Please make sure your email address is always correct.
If your available Survey Response balance hits below zero your participants won't be able to answer your survey(s) anymore and we will send another email to you.
If you are using the FREE plan, then your access to LimeSurvey will be locked completely. In that case, you will have to wait until the end of your month period for it to get unlocked automatically or buy a subscription plan.
Survey participants might be sceptical or careful due to the LimeSurvey Professional url in the address bar, e.g. following a click on a survey link from your website/invitation email, the url changes to ‘yourdomain.limequery.com’.
Domain aliasing allows you to use your own website domain for your survey.
Your regular website is http://www.mydomain.com. Your LimeService installation is at http://mydomain.limequery.com. . By using domain aliasing you can e.g. use http://survey.mydomain.com for the LimeSurvey installation so that your participants only get to see this domain in their address bar.
Domain aliasing is only available as part of the EXPERT or ENTERPRISE subscription.
This is how it works:
- Open the administration panel of your domain/hosting provider where you host mydomain.com and search for the DNS settings. Change or create a DNS ‘A’ entry for your preferred domain name (for example ‘survey.mydomain.com’) and have it connect to the IP address of your LimeService installation. You can find out the IP address by opening a console window and typing 'ping yoursubdomain.limequery.com'.
- Edit your LimeSurvey Professional settings and add your preferred domain name (without http://), for example ‘survey.mydomain.com’
- SSL & alias domains: We strongly recommend that you conduct all surveys with SSL (https). If you use an alias domain, our system will try to automatically create an SSL key using Let's Encrypt. Note that this only works if the DNS entry is properly set (see step 1). Every time you save the alias domain URL in your LimeSurvey Professional profile settings our system will try again to retrieve a key from Let's Encrypt.
- Alias URL in invitation/reminder emails: To fullly use the new alias domain URL for your invitation/reminder emails just log in at the administration URL of the alias domain domain, e.g. http://yoursubdomain.limequery.com/admin
- It is not possible to set an alias to specific subpages/paths (such as http://www.mydomain.com/test/test.html), only full domain names are allowed. In most cases a subdomain is the best choice, but root domains are also okay.
In case you have any further questions, don’t hesitate to use our support system.
Please visit your community profile
, then can click on then button labelled 'Update your profile'.
On editing the profile you will find a button that is labeled with 'Delete my account'. Click that button and confirm the deletion.
We are trying our best to keep your installation available at all times and guarantee a 99% uptime. If there is a reason to temporarily shut down the survey facilities, we will let you know in advance either by email (for a scheduled maintenance) or on the LimeSurvey.org homepage (for emergency maintenance).
Yes. Generally, that is possible without any problems. There is one important thing though: You can't import files from a version newer than the version LimeSurvey is using, but usually, LimeSurvey Professional always offers the latest stable version. Currently, you can import surveys from any LimeSurvey version 1.91+ or newer. Note that you can download any past LimeSurvey version from the LimeSurvey download area.
We offer the following payments types.
- VISA Card
- MasterCard Card
- For some countries: SEPA payments
- For selected customers: Payment on account/invoice / Purchase Order (PO) - contact us.
All of the above payments are handled by our payments providers PayOne or Paypal. Please note that if you choose Paypal, you need to own/register a Paypal account for subscription payment.
Everytime a product is billed you will get an automatically generated invoice sent to your email address. Furthermore, you can see all past invoices in your profile billing page.
When sending invitiations or reminders for your survey you have two choices:
1.) Using our mail server
If you are using the LimeSurvey Professional mail server, all your emails will have the sender address email@example.com. However, these emails will have a Reply-to header with your email address. So in case someone tries to reply they will write to you directly.
Although this method is set up very quickly (just enter global settings and set 'LimeSurvey' as your preferred mail type) it has one downside: If an email cannot be transmitted to the email receiver and bounces back, then you won't get any notifications whatsoever.
Please don't abuse LimeSurvey for spam or we will have to lock your account. Make sure that you have the general consent of people you want to send invitations to.
2.) Using your own SMTP server
This method has the advantage that you can send all email invitations and reminders using your own sender address and you will get bounced emails back. Most email and hosting providers offer SMTP to send emails. The only thing for you to find out is how to send an email via that SMTP - by figuring out the following details:
- Email address (which is allowed to send using that server)
- SMTP user name (in many cases this is the same as the email address)
- SMTP host name
- Does your SMTP require an SSL or TLS connection? If yes, also find out which port it is.
Then enter the global settings dialog in your LimeSurvey installation and go to the email tab - enter the required data. If your SMTP server is using a special port, then attach it to the host name with a colon. For example, if your host name is 'smtp.server.net' and the port is 143, then write 'smtp.server.net:143' as host name. For security reasons we currently only allow the following ports numbers: 110, 143, 587, 993 and 995.
After you save the new settings make sure that you enter that same valid email address in the survey settings of your survey.
Now it should all be running fine.
A note to email server administrators:
LimeSurvey will initialize the SMTP connection from the IP address of your LimeSurvey installation. Just ping the URL of the LimeSurvey installation to find out which one it is. In case you have your SMTP server locked down you will need to add this IP address as an exception to your SMTP configuration/firewall.
You can cancel your subscription by logging into the LimeSurvey website, go to you profile page
click on 'Billing' in the left menu, then on 'Orders'.
There you will see all your active subscriptions and you can cancel each of them with two clicks.
A key expires either if the expiration date or the maximum number of uses for that key has been reached. One use is counted when you update to the latest version/build ComfortUpdate.
Yes, you can. Again, please note that each key has a maximum number of uses/updates assigned to it. See the previous FAQ item.
LimeSurvey is not a non-profit association - because of that you will receive a normal invoice (if applicable including VAT) after payment. If are not a registered LimeSurvey user you will receive this automatically by email. The invoice item on the invoice will be 'LimeSurvey Support'. If you are a company you will be able to use this invoice as any other invoice you receive.
If you have a LimeSurvey account: Just click on 'Your orders
' in the user menu and you will be able to see your past donations/invoices.
All your donations during the last 12 months are cumulated for the ranking. This total sum is used to determine your ranking:
- between 1€ and 30€: Bronze Donator
- between 31€ and 75€: Silver Donator
- between 76€ and 250€: Gold Donator
- more than 250€: Platinum Donator
Yes, we offer an automatic quotation system.
Just choose the product you want a quotation for and click on 'Order now'.
In the form you can select the checkbox 'Request quotation'.
Then just checkout normally. the quotation will be sent to your registered email address.
In the top-right corner of the admin interface you can see how much storage you are using and how much your maximum storage limit is.
Every file you or your participants upload to the installation (like pictures, documents or possibly videos) is included here.
If you exceed the storage limit, all surveys which contains file upload question types will be locked and you will not be able to upload further files in the administration.
If you delete responses and surveys, the space occupied by those items will be freed. If you want to keep the uploaded files, please observe that they will not be included in an exported survey archive file (*.lsa)!
You have to manually go to response browsing and select files you want to download. See picture.
When you've saved all the files you want to keep, you can start to remove files. Uploaded files will be deleted together with a response, but it's also possible to delete the files without deleting the response by clicking on the button with the red paper clip.
To delete multiple files at once, check the responses which files you want to delete and then click the red paper clip icon in the massive action menu.
Templates and label sets are deleted in the template editor and label sets manager, respectively.
After you've deleted data, make sure to go to global settings, the storage tab, and click on "Calculate storage" to update your storage counter.
When your storage exceeds the allowed limit of your subscription package, all surveys which contain upload question types will be blocked.
Also you will not be able to upload files for your survey content anymore.
To unlock these surveys/unblock the file contact you have to free up space by deleting old surveys (having file upload questions) and/or their responses.
Storage reminder percentage is a setting in your installation profile.
This setting controls when your storage alert e-mail will be sent out. As an example, say you enter the value 10 (10%, default value) and have 100 MB total storage (Basic package). When your used storage reaches 90 MB (10% space left), an e-mail will be sent out to the administrator of the installation. If you entered the value 50, the warning would be send out when half of your storage is used, and so on.
See the other FAQ items about storage for more information about which actions to take when your storage reaches its limit.
If you go to global setting, there's a storage tab:
Click on the button "Calculate storage" and the page will show you how much space your surveys, templates and labels take up:
After you've deleted data, make sure to go to global settings, the storage tab, and click on "Calculate storage" to update your storage counter. It might take a few seconds to come into effect. Just reload the page to see the new storage count.
If you just would like to delete your LimeSurvey Professiona installation please follow these steps:
- Navigate to your profile page to see an overview of all you installations.
- Click the 'Edit' button.
- On the bottom of that next page there is a big red button 'Delete now'. Click on it, read the warning and its implcation and confirm the deletion.
Please note that on deleting an installation any existing subcription will be cancelled and cannot be used anymore.
All data provided by your or your participants inside that LimeSurvey installation will be lost.
If you are using our LimeSurvey Professional hosting:
When creating your LimeSurvey Professional instance, you will be asked for the server location, where we will host your data. At the moment we offer the following hosting location:
- Germany (recommended in general for EU customers)
- United Kingdom
After selecting a location, we will store your data exclusively on a server in that country.
We are not using cloud services so we can always exactly determine which server your data is stored on.
If you are using our LimeSurvey Community Edition:
In that case all your data is stored on your or your provider’s server (usually the one where you installed LimeSurvey).
In general, we are mostly GDPR compatible – we are just working to set up the proper contracting procedure which will be available until May 2018. We will notify all our customer accordingly as soon as it is available.
To be compatible with the GDPR & EU law in general we strongly recommend to select our German server as server location as it is the only server location where we can guarantee full EU GDPR compliance for the future.
Yes. We offer on online contracting tool where you can quickly create the necessary contract with a few clicks yourself and download the resulting contract as PDF - the resulting document is already signed by us.
You can find the tool here: In your LimeSurvey website profile click on the menu entry GDPR agreements in the left menu.
Disclaimer: This is not a legal advice, so if in doubt ask a lawyer.
We think it is not necessary to show a Cookie consent form. Here is a related excerpt from the EU commission website The EU Internet Handbook:
LimeSurvey is clearly covered by this case. In general, you can say without a cookie it would not be possible to run a normal online survey safely that spreads over several pages.
Yes. Starting with LimeSurvey 3.4.x you will be able to insert a survey policy in the survey settings and require the user to agree to that by checking a box.
We do not offer a template for that. The data protection policy/law is very different for each country and also the type of data your collecting in our survey(s) has a big influence on how the policy should look like and what is allowed/required. Please contact your data protection officer or a lawyer to find out how such a policy should look like for your specific survey(s).
We are very concerned about security. Your survey/response data is stored in a separate database with a separate user name/password for each LimeSurvey Professional installation. The connection is encrypted if you are using SSL connections (that is the default – visible by https:// prepending your survey links).
The data inside LimeSurvey is not encrypted because it is regularly accessed by the LimeSurvey application (it is not at rest).
However, we create daily backups of your LimeSurvey data. That data is at rest and encrypted, stored safely on a different server, but at the same hosting location.
