Privacy
Here is exactly what is protected and how, without promising more than the app really does.
Your notes: encrypted, unreadable to us
The notes you write during a test are encrypted on your device (AES-256-GCM) with a key protected by your 6-digit code (PBKDF2 derivation). Our server never receives that code or the plain key: without your code, your notes are unreadable, including to us. If you forget your code, we can’t recover them.
Your answers: stored on your account
Your scale answers (the numbers you tick) and MMMask’s readings are stored on your account, not encrypted with your code: they are used to compute and show your results again. The database access rules make them readable by your account only, from the app.
AI: only if you choose it
If you choose MMMask’s reading, your answers and notes (decrypted on your device) are sent to our server and then to our AI provider (OpenAI), only to generate that reading. Without that choice, nothing is sent to an AI. The provider handles this data under its own API terms.
Your account
We keep your email address (and, if you sign in with Google, the identifier Google provides) so you can log in. Your PIN never leaves your device.
Cookies
Technical cookies only: your login session and your language. No advertising cookies, no analytics. The key that decrypts your notes stays in the tab’s memory and disappears when you close it.
Service providers
Database and login: Supabase, Inc.. AI reading (only on request): OpenAI. No data is sold or used for advertising.
Your rights
You can ask for access to your data, its correction, an export, or the deletion of your account and all your data by writing to contact@oxymammoth.com. Your data is kept as long as your account exists. You can also contact your country’s data protection authority.
What MoiMoiMoi is not
MoiMoiMoi is an introspection tool. The tests and MMMask’s readings are not a medical or psychological diagnosis and do not replace the advice of a health professional.
A score shows your position on an instrument’s scale, not a comparison with a population or a label. MMMask is an AI: it can be wrong.
If you’re not okay
If you are going through a hard time or having suicidal thoughts, talk to someone. US: 988 (Suicide & Crisis Lifeline). UK and Ireland: 116 123 (Samaritans). Emergencies: your local emergency number (112 in the EU).
