Privacy Policy
Effective 2026-11-14
Summary
Snacklingo (https://snacklingo.app) is a language-learning app. You can use it without an account, in which case nothing about you is stored on our servers. If you sign in, we store your email address and your learning progress so it follows you across devices. We do not show ads, sell data, or use tracking or analytics cookies.
What we collect
Without an account:
- Learning progress (lessons finished, XP, streak, cookies, coins, chosen languages) is kept only in your browser's storage on your device.
If you sign in:
- Your email address.
- If you use Google sign-in: the name and profile picture address that Google provides with your email. We do not get your Google password or access to anything else in your Google account.
- Your learning progress, as listed above.
- A nickname, if you set one.
- Sign-in times, kept by the sign-in service.
Like any website, the hosting provider processes technical data such as IP address and browser type to deliver pages and protect the service.
What is public
If you are signed in and earn XP, your nickname and your XP for the current week appear on the weekly ranking, which anyone can view. If you have not set a nickname, a generated name such as “Snacker-1a2b” is shown. Your email address is never shown.
Why we use it
- To sign you in and keep your account secure.
- To save your progress and restore it on other devices.
- To show the weekly ranking.
- To answer you when you contact us.
Who processes it for us
- Supabase — sign-in and database. Data is stored in the Tokyo (Japan) region.
- Cloudflare — website hosting and delivery.
- Google — only if you choose Google sign-in.
- Resend — sends the sign-in email, only if you choose email sign-in. It receives your email address.
These providers act on our behalf. We do not sell or rent your personal data, and we do not share it for advertising.
Storage on your device
The app uses your browser's local storage to keep your progress and, if you sign in, to keep you signed in. This is needed for the app to work. We do not use advertising or analytics cookies.
How long we keep it
We keep account data until you ask us to delete it. Ranking entries are kept per week. Logging out clears the progress stored on that device; the copy on our servers remains so you can sign in again.
Your choices
You can ask for a copy of your data, a correction, or deletion of your account and everything linked to it by writing to hello@snacklingo.app from the email address on your account. We will act on the request within 30 days. You can change your nickname at any time on the profile page.
Children
The service is not directed at children under the age at which they can consent to data processing in their country (14 in South Korea, 13 in the United States, 13 to 16 in the EU). If you are younger, please use the app without an account or with the consent of a parent or guardian.
Changes and contact
If this policy changes, the effective date above will be updated, and significant changes will be announced in the app. Questions: hello@snacklingo.app.
