Overview
Last updated: 10 November 2026.
This Cookie Policy explains how synaps GmbH ("Company," "we," "us," and "our") uses cookies and similar technologies on our website at https://synaps.app ("Website") and in our app at https://my.synaps.app and other Synaps subdomains ("Platform"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.
In some cases we may use cookies to collect personal information, or information that becomes personal information if we combine it with other information. Our Privacy Policy at synaps.app/privacy explains how we handle that information.
What are cookies and similar technologies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.
Cookies set by the website owner (in this case, synaps GmbH) are called "first-party cookies." Cookies set by parties other than the website owner are called "third-party cookies." Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g., analytics, advertising measurement). The parties that set these third-party cookies can recognize your computer both when it visits the website in question and when it visits certain other websites.
We also use similar technologies that store information in your browser: local storage, session storage, IndexedDB and the browser cache. This policy calls them all "cookies" unless the difference matters.
Why do we use cookies?
We use first- and third-party cookies for three purposes. Some cookies are required for technical reasons in order for our Website and Platform to operate, and we refer to these as "necessary" cookies. Analytics cookies help us understand how the Website and Platform are used so we can improve them. Advertising cookies let us measure our own advertising and reach people who are likely to be interested in Synaps. Each is described in more detail below.
Whether optional cookies are set before you choose depends on where you are. In the EU and the rest of the EEA (including the EU outermost regions and Åland), the UK and Switzerland, when we cannot tell your country, or when your browser sends a Global Privacy Control signal, Analytics and Advertising cookies are only set if you allow them. Elsewhere, they are set from your first visit until you choose Reject all.
How can I control cookies?
You have the right to decide whether to accept or reject cookies. When you first visit, a consent bar offers Reject all, Accept all and Manage. Manage shows the three categories: Necessary, which is always on and cannot be refused; Analytics; and Advertising. Switch on the categories you allow and choose Accept, choose Reject all to refuse both optional categories, or choose Accept all to allow everything.
You can change your mind at any time. On the Website, choose Cookie settings in the footer to reopen the categories. In the Platform, open Settings, then Privacy. Your choice is stored in a consent cookie on synaps.app, so the Website and the Platform share one answer and you are not asked twice. If you are signed in, the choice is also stored on your account and follows you to other devices. If you reject optional cookies, you can still use the Website and the Platform in full. You may also set or amend your web browser controls to accept or refuse cookies.
The specific cookies we use and their purposes are described below. The cookies served may vary depending on the pages you visit and the features you use.
Necessary cookies
These are required for the Website and Platform to work: signing in, keeping your session secure, remembering your cookie choice, and keeping your work safe. They cannot be switched off.
- synaps_analytics_consent and synaps_analytics_consent_record: your analytics choice. First party, 1 year.
- synaps_advertising_consent: your advertising choice. First party, 1 year.
- synaps_consent_region: whether your country requires consent before analytics and advertising (strict or default-on), never the country itself. First party, 24 hours.
- Supabase sign-in session (local storage, Platform): keeps you signed in. Kept until you sign out.
- synaps-document-sync (IndexedDB, Platform): drawing edits that have not reached our servers yet, so that they are not lost if your connection drops. Removed once they are saved.
- cad-clipboard-mirror (IndexedDB and local storage, Platform): drawing content you copy, so that you can paste it in another tab. Cleared when you sign out.
- assets-v1 (browser cache, Platform): copies of project files and images, so that projects open quickly and work offline. Kept until your browser clears it.
- Display preferences (local storage, Platform): settings such as panel layout, units and the last view position of each page. Kept until you clear them.
- synaps:session_started and synaps:access_revoked (session storage, Platform): the state of the current browser session. Cleared when you close the tab.
- synaps-nav (session storage, Website): smooths the transition between pages. Cleared when you close the tab.
- synaps.assistant.draft (local storage, Website): a question you have typed into the product assistant but not sent, so that it is still there when you return. Kept until you clear it.
- synaps.onboarding.brief (local storage, Website): a building description you start in the product assistant, handed to the Platform when you sign up. Kept until you clear it.
Analytics cookies
These cookies collect information that helps us understand how our Website and Platform are being used, so we can improve them. When you are signed in, PostHog links this information to your account.
- PostHog (ph_* cookies and local storage): product analytics and, in the Platform when you have actively allowed Analytics, session replay. Hosted for us by PostHog in the EU. First party on synaps.app, up to 1 year.
- synaps:has_visited, synaps:onboarding_outcome and synaps:edit_kept (local storage, Platform): records of one-time product events that have already been sent, so that they are not counted twice. Kept until you clear them, and only read while Analytics is allowed.
- Google Analytics (_ga, _ga_*): usage statistics for the Website and Platform. Set by Google, up to 2 years.
On the Website, after you refuse Analytics, PostHog counts visits without cookies or other storage on your device, using an identifier calculated on its servers that changes daily.
Advertising cookies
These cookies let us measure whether our advertising works and reach people who are likely to be interested in Synaps. They are only set if you allow Advertising. When you allow them, we share signals about your visit and your use of Synaps, such as whether you signed up, started a trial or used an AI feature, with Google Ireland Limited for Google Ads and Meta Platforms Ireland Limited for Meta advertising. Google may transfer this data to the United States; that transfer is covered by the EU-US Data Privacy Framework and Google's standard contractual clauses.
- Meta Pixel (_fbp, _fbc): browser and advertising click identifiers used for conversion measurement and ad attribution. First-party cookies, generally up to 90 days; browser restrictions can shorten this.
- synaps_attribution: the first consented landing page, referrer and campaign tags, shared between the Website and Platform for up to 90 days. The Website stores this cookie only with Advertising consent, or outside the EU, the EEA, the UK and Switzerland until you choose Reject all, and removes it on withdrawal. The Platform can also retain campaign tags with Analytics consent; Google and Meta click identifiers require Advertising consent.
- Google Ads (_gcl_au, _gcl_aw): conversion measurement and attribution. Set by Google, up to 90 days.
If you refuse Advertising, Meta Pixel and Conversions API are disabled. Google Consent Mode may send cookieless measurement pings with storage and advertising consent signals denied. You can choose Analytics without Advertising. Choosing Advertising also selects Analytics in the consent controls because our product conversion measurement uses both.
Other requests to third parties
Some features contact third parties without setting cookies. The Platform loads fonts from Google Fonts and rsms.me. When you search for a place in the Site tool, your browser contacts MapTiler for search results and map images. These requests share your IP address and browser information with those services. Our Privacy Policy describes them.
How can I control cookies on my browser?
As the means by which you can refuse cookies through your web browser controls vary from browser to browser, you should visit your browser's help menu for more information. The following is information about how to manage cookies on the most popular browsers:
- Chrome
- Firefox
- Safari
- Edge
- Opera
Clearing your browser's site data removes cookies and other stored information, including drawing edits that have not been saved to our servers yet. Make sure your work is saved first.
In addition, most advertising networks offer you a way to opt out of targeted advertising. If you would like to find out more information, please visit:
- Digital Advertising Alliance
- Digital Advertising Alliance of Canada
- European Interactive Digital Advertising Alliance
What about other tracking technologies, like web beacons?
Cookies are not the only way to recognize or track visitors to a website. We may use other, similar technologies from time to time, like web beacons (sometimes called "tracking pixels" or "clear gifs"). These are tiny graphics files that contain a unique identifier that enables us to recognize when someone has visited our Website or opened an email including them. This allows us, for example, to monitor the traffic patterns of users from one page within a website to another, to deliver or communicate with cookies, to understand whether you have come to the website from an online advertisement displayed on a third-party website, to improve site performance, and to measure the success of email marketing campaigns. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.
Do you serve targeted advertising?
We do not show advertisements on our Website or Platform. If you allow Advertising cookies, we share signals with Google and Meta so that we can measure our own advertising on their services and reach people likely to be interested in Synaps. You can refuse this at any time through Cookie settings in the footer or, in the Platform, under Settings, then Privacy.
How often will you update this Cookie Policy?
We may update this Cookie Policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please therefore revisit this Cookie Policy regularly to stay informed about our use of cookies and related technologies.
The date at the top of this Cookie Policy indicates when it was last updated.
Where can I get further information?
If you have any questions about our use of cookies or other technologies, please email us at [email protected] or write to synaps GmbH, Seitenstettengasse 5/37, 1010 Vienna, Austria.
