MiMem — Privacy policy

Last updated 14 November 2026. This version covers the closed test of MiMem on Google Play.

Who we are. MiMem is published by Gayathri S, an individual developer in Bengaluru, India. Contact and grievance officer (India, DPDP Act 2023): Gayathri S, keepinmem.app@gmail.com.

What MiMem keeps, and where

• Your notes, voice notes, the text of your photos and documents, imported chats and calendar events are kept on your phone only, in an encrypted database. We have no copy, and there is no account.
• Photos and documents stay where they are (your gallery, Downloads); MiMem keeps only their text and a link to them.
• Voice is written down on your phone; recordings are not kept once written.

What leaves your phone, and only when

1. Answers written by the cloud AI (your choice; on only after you agree): your question and the parts of your memories needed to answer it are sent, through our server, to Anthropic's Claude AI in the United States, which writes the answer. Each memory you save is also read once by the cloud AI to find dates for "Coming up". Choose "Phone AI only" and nothing is sent.
   • Our server (Cloudflare) passes the request on and keeps nothing but a count of requests per phone per day, under a random number that is not linked to you.
   • Anthropic does not use this data to train its models; it may keep it for a limited time for safety and abuse review, under its commercial terms.
2. Your calendar (only if you turn on adding reminders to your calendar): reminders you confirm are written to the calendar you choose, which syncs on that calendar account's terms.
3. Sharing (only when you tap Share): the memory goes to the app you pick, on that app's terms.
4. Downloads: the phone AI and voice models are downloaded from GitHub; no personal data is sent with them.
5. Photo descriptions (only if you turn it on): a photo with no words on it is sent once to the cloud AI, which writes a short description so you can find it later. Nothing is kept by us.
6. Tamil voice (only if you choose Tamil and allow it): your speech may be written down by Google's speech service; with Google's offline Tamil pack it stays on the phone.
7. Reporting a wrong answer (only when you tap it): your own mail app opens with the question and the answer; you see everything before you send it.

What we never do

Sell or rent your data; show ads; track you across apps; build a profile of you.

Private memories

A memory you make private is hidden everywhere in the app, and never sent to the cloud AI while hidden, until you show it again with your phone's own fingerprint or screen lock.

Other people and children

Your memories may name family and friends; they stay on your phone and, with the cloud AI on, only the parts needed for an answer are sent as above. MiMem is for adults (18+).

Your choices

Switch the cloud AI off any time (Settings → Answers → Phone AI only). Delete any memory, or everything in Settings. Uninstalling removes all of MiMem's data from the phone. Back up to a file you keep, encrypted with your password.

Security

The database is encrypted with a key kept in the phone's secure hardware; data in transit is encrypted (TLS). A phone that is unlocked in someone else's hands, or one with malware, can expose what is on it.

Deleting your data

Everything is on your phone: delete it in the app or uninstall the app. Our server holds only the random number and its daily count, which you can ask us to delete at the address above.

Changes

We will show changes in the app before they apply.

Terms of use

1. What MiMem is. A personal memory app: it keeps what you save and answers your questions from it.
2. Answers can be wrong. They are written by an AI from your memories; check anything important (health, money, legal, dates) against the memory itself, which each answer shows.
3. Your content is yours. You are responsible for what you save and share.
4. Fair use of the cloud AI. A daily limit per phone applies; not for automated or unlawful use; Anthropic's usage policy applies to what is sent.
5. No warranty. MiMem is a test version provided as it is; to the extent the law allows, we are not liable for losses from relying on an answer or from lost data. Keep backups.
6. The phone's AI model. MiMem's on-phone AI is Google's Gemma, used under the Gemma Terms of Use; you agree not to use it for anything the Gemma Prohibited Use Policy forbids.
7. Law. The laws of India; courts of Bengaluru.
