Cinnamon Privacy Policy

Last updated 14 September 2026

Cinnamon is a free language-learning app published by Vishal Bhanderi, Germany ("we", "us"). This policy explains what data the app collects, why, and how you can delete it.

What we collect

Data	Why
Name and email address (and profile picture, if you sign in with Google)	To create and identify your account
Password, if you sign up with email	To sign you in. Stored only as a salted hash
Learning profile: native language, language you are learning, level, motivation, daily goal	To choose your course and daily plan
Learning progress: words reviewed, answers, review schedule, articles read	To schedule your reviews and keep your progress across devices

Microphone

Voice practice is optional and asks for microphone access only when you turn it on. Your speech is converted to text by your device's speech recognition service. Cinnamon does not record, store, or upload audio.

What we do not do

We do not show ads, use your advertising ID, or track you across other apps and websites.
We do not sell or share your personal data with advertisers or data brokers.
We do not collect your contacts, photos, location, or payment information.

Service providers

These providers process data only to run their part of the app:

Vercel — hosts our backend and database.
Google Firebase — Google Sign-In.
Microsoft Azure AI and other AI providers — generate audio and word translations. Only the text needed for the request is sent, never your name or email.

How long we keep it

We keep your account and learning data while your account exists. When you delete your account, it is removed from our servers immediately and from backups within 90 days.
