What we collect
Your email address. You sign in with Google or with a one-time email code.
Your settings: the language you practise, your level, your native language, how you want to be corrected, the tutor's voice and speed, and your daily goal.
Your conversations: what you type, and in a call the written transcript of what you say, the tutor's replies, the suggestions on your lines, your reports, your review cards and new words.
What the tutor remembers about you, only if you turn memory on (see below).
Daily counts of how much you used, such as turns, voice seconds and characters spoken. They hold numbers only, never your words, and keep the free allowance fair.
When a new account signs in for the first time, a keyed fingerprint of the network address, so one network cannot open endless accounts. The address itself is not stored.
Basic technical information that comes with every visit, such as your IP address and browser type. We use it to keep the app secure and to find faults.
Your voice
Snak does not store your voice. ElevenLabs processes it and may keep it under its own policy (elevenlabs.io/privacy-policy).
Only the written transcript of what you said is saved, in your conversation, so you can see your mistakes and the report.
This first version gives no pronunciation scores. It corrects grammar, word choice and style.
Why we use it
To give you an account and run the tutor for you: replies, corrections, reports and review drills. This is the agreement between you and us.
To keep the app secure, working and affordable: the daily allowance and the limits on new accounts. This is our legitimate interest in running a safe service.
We do not sell your data and we do not use it for advertising.
Who processes your data
We use these companies to run the app. They handle your data only on our behalf.
Requests to the AI model go through OpenRouter to Anthropic with data collection switched off (data_collection: deny), so your conversations are not used to train models.
| Company | What it does | Data it handles |
|---|---|---|
| ElevenLabs | Turns your voice into text in a call, and the tutor's text into speech | Your voice while it is turned into text, and the tutor's reply text |
| OpenRouter | Routes the conversation to Anthropic's model, which writes the tutor's replies, checks your language and writes your report | The text of your conversation |
| Supabase | Stores your account and data in the EU, and handles sign-in | Email, settings, transcripts, corrections, reports, review cards, memory |
| Vercel | Hosts the app and delivers its pages | Technical information about each visit |
Memory
Memory is off unless you turn it on in Settings. When it is on, the tutor keeps a few short facts you mention (for example your job or a hobby) so later conversations can build on them. It never keeps contact details.
You can see what is remembered and clear it in Settings at any time. Turning memory off stops anything new being kept.
How long we keep it
Transcripts are kept until you delete the conversation or your account. Every conversation has Delete in its menu.
When you delete your account in Settings, your conversations, reports, review cards, words, memory and settings are removed. The daily usage counts stay, because deleting must not reset the free allowance; they hold numbers only.
Copies of the tutor's voice for lines played more than once are shared between learners and hold no personal data: they are stored under a code made from the words, not under your name.
Our hosting provider keeps technical logs for a short time, then removes them. Our logs never contain what you said or typed.
Your rights
You can ask to see your data, correct it or have it deleted. You can delete your account yourself at any time in Settings.
You can ask us for a copy of your data by email.
If you think we handle your data wrongly, you can complain to the data protection authority in your country.
Cookies
We use only the cookies the app needs: one to keep you signed in and one to remember your choices, such as light or dark mode. There is no advertising or tracking cookie.
Children
This app is not meant for children under 16. If you think a child has made an account, contact us and we will delete it.
Changes
If we change this policy, the date at the top changes. For big changes we will tell you in the app or by email.
