Privacy policy
Last updated 29 September 2026
In Felt you write or speak about things that matter to you. So this page says exactly what the app keeps, who can see it, and how to remove it. No small print that says something different from what is here.
Who is responsible
Felt is an app by RS Website Studio, the sole-trader business of Rob Swagten, registered with the Dutch Chamber of Commerce (KvK) under number 70949654, at Titiaanstraat 28-2, 1077 RH Amsterdam, the Netherlands.
Questions about your data go to hello@robswagten.com. Rob answers himself, within a month and usually much sooner.
What Felt keeps
What you write and say. Your conversations, your topics, what you keep in a topic or in Embody, your notes on what you read, and your practice sessions. This is the heart of the app: it keeps them so you can come back to them.
What the app makes of it. At the end of a conversation the app may name what seems to lie underneath, "as far as this can tell". That is an estimate, not a finding about who you are. You can correct it.
Whether you are in therapy. Only if you say so yourself, and only which kind.
A safety check. Every message is read by a separate AI check for signs of a crisis. If it sees any, the conversation pauses and you are shown numbers to call. That moment is recorded.
Your account. Your email address, or a private relay address from Apple if you sign in with Apple and hide your address. This is held by Clerk, the service that handles signing in, not in the database with your conversations. That database holds only a code that links the two.
Technical data every app has. When you sign in and with every request to our server, your IP address and the kind of device arrive with it. Crash reports carry a code for your account, but never what you wrote: the app removes that text before a report is sent.
What Felt does not keep. Your name (the app does not ask for it), your phone number, your location, your contacts. The app's reminders are notifications your phone makes itself; nothing goes to a notification service.
Why, and on what basis
The law asks for a basis for every use of personal data. Because what you write in Felt is about your feelings and your life, the law counts it as special category data: data that gets extra protection.
| What | Why | Basis |
|---|---|---|
| Your conversations and what you keep | Because that is what the app does | The agreement with you (you use the app), and for the sensitive content your explicit consent, given at "Before you start" |
| Turning speech into text | Only when you speak instead of type | Your explicit consent, asked separately the first time you speak |
| The safety check | To point you to help when it is needed | Your explicit consent (as above), and your vital interests |
| Your account | To sign in | The agreement with you |
| Crash reports, updates, loading the library, keeping track of what the AI costs | To keep the app working and affordable | Legitimate interest: an app that works. Your words are never used for this |
| During the test: reading conversations and measuring use | See "During the test" below | Your consent, asked separately for each |
You can withdraw consent at any time. The app then stops doing what you no longer want; what was already done on the basis of your earlier consent remains lawful.
Who else sees it
Felt does not sell your data, shows no advertising, and passes nothing to advertisers or data brokers. Felt does work with services that process data on Felt's behalf and only for Felt. With each of them a data processing agreement applies: a contract that says they use your data only to provide their service.
| Service | What they do | What they receive | Where |
|---|---|---|---|
| Anthropic | The AI, Claude, that asks your questions back | The text of the conversation. Not your name, email or account: the app sends only the words | Worldwide (cloud) |
| Speechmatics | Turning speech into text | Your recording and your IP address | European server |
| Supabase | The database and the server | Everything the app keeps | Ireland |
| Clerk | Signing in | Your email address, IP address and device | United States |
| Sentry | Crash reports | The crash, with an account code, without your words | European Union |
| Sanity | Delivering the library | Your IP address when the app fetches a piece | Not stated |
| Expo | App updates | Your IP address and the app version | Not stated |
| Apple | Sign in with Apple, if you choose it | That you sign in to Felt | Apple |
Anthropic does not train its AI on your conversations. Its commercial terms say so.
Outside Europe
Anthropic, Clerk and Sentry are American companies; for Sanity and Expo the server location is not stated. Where data leaves the European Union, it does so under the arrangements the European Commission has approved for that: the Standard Contractual Clauses, and for Clerk, Sentry and Expo also the EU-US Data Privacy Framework. These oblige the receiver to protect your data as well as it is protected in Europe.
How long
| What | How long |
|---|---|
| What you write and say, and everything the app makes of it | As long as your account exists. When you delete your account it is gone: truly deleted, not hidden |
| Your sign-in details at Clerk | Until you delete your account: they are deleted with it, at once |
| At Anthropic | At most 30 days, then deleted automatically |
| Your recording at Speechmatics | At most 7 days. The app itself does not keep the recording |
| Server logs with your IP address | About a day |
| Crash reports at Sentry | At most 90 days |
| During the test: measuring use | Until a year after the test ends, or at once when you switch it off |
Your rights
You have the right to see your data, have it corrected or deleted, take it with you, object, or withdraw your consent. In Felt:
- See it and take it with you: Account → Download your data makes one file with everything the app has about you.
- Correct it: most things you change in the app itself; what the app saw underneath, you can correct.
- Delete it: Account → Delete my account, confirmed twice. Or email Rob and it is deleted, all of it, not hidden.
- Withdraw consent: for speech, by typing instead; for the test questions, with a checkbox in Account → Privacy and research; for everything else, by deleting your account or emailing Rob.
If you and Felt cannot resolve something, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl).
During the test
Felt is being tested with a small group of people. Rob asks you two things during the test, each switched on or off separately, and the app works exactly the same if you say no:
- Reading conversations. Rob may read your conversations to learn how the app should change, without your name, email or account attached: you appear as "Tester" with a code that cannot be traced back to you. Please note: someone who knows you can sometimes recognise you from what you write. Nothing is ever published or shared.
- Measuring use. Which parts of the app you use and for how long, never what you write or search for.
More about this is in the information letter you receive with the test.
Security
Your data is stored encrypted and travels encrypted over the internet. The database shows each person only their own data. The AI is called from our server, not from your phone, so Anthropic does not see your IP address.
Age
Felt is for people aged 18 and over.
Changes
If anything changes about what Felt keeps or who sees it, Rob updates this policy and you see it in the app before it takes effect.
