Privacy Policy

Effective date: August 14, 2026

This Privacy Policy explains what information Memori (“Memori”, “we”, “us”) collects, how we use it, and the choices you have. It applies to the Memori mobile app and the services behind it.

We have tried to write this plainly. If anything is unclear, email us at [email protected] and we will explain.

The short version

Information we collect

Account information. If you create an account, we store your email address and an encrypted password (handled by our authentication provider — we never see your password in plain text). You can also use Memori through an anonymous account, which has no email address and no personal identifier beyond a random ID; it exists only so your deck can be backed up before you sign up.

Your learning content. The material you create and study: topics, chat conversations with the AI tutor, flashcards, review history, and your study settings. This is stored so it can sync across sessions and be restored if you reinstall.

Payment information. If you subscribe to Memori Pro, payment is processed by Google Play or the Apple App Store, with a subscription-management provider tracking your subscription status. Memori never receives or stores your card number — the store handles the payment details, and we receive only your subscription status and a purchase reference.

Usage counters. We keep simple daily counters of how much of the AI features you have used, so we can apply fair-use rate limits. These are counts, not a log of what you asked.

Reports and blocks. If you report a shared deck, we store which deck it was and its title, a copy of that deck's cards as the person who shared it published them, the reason you chose, any note you wrote, the account that published it, the account that filed the report, and your app version and platform — so a person can look at what was actually shared and decide what to do. We keep our own copy of those cards because a shared deck can be edited and re-shared after it is reported, and a report has to be about the deck as it was when you saw it. Your own imported copy of a deck is never sent to us when you report it. If you report a tutor reply, we store that reply and the question that produced it, along with your reason, any note, your app version and platform; the report carries no link back to the conversation it came from, and no other part of the conversation travels with it. If you block a deck's source, we store that your account has blocked that account, so we can stop its decks reaching you.

Diagnostics. When the app hits an error or crash, we send a crash/error report to a third-party diagnostics provider so we can find and fix bugs. These reports can include technical details about the failure and your device.

How we use your information

Where your data goes (service providers)

Memori relies on a small set of providers to run. We share only what each one needs to do its job.

Data storage and retention

Your account and learning content are retained for as long as your account exists so the app can back them up and restore them. Some technical caches (such as synthesized audio) are shared and content-addressed rather than tied to your account.

Reports are kept while we may still need to act on them and to enforce our Terms. A report about a shared deck records which account published it, so that repeated abuse can be acted on even after the deck itself has been deleted. If that account is later deleted, the link to it is removed from the report, but the report and its copy of the shared cards are kept.

Deleting your data

Signing out of Memori clears your data from that device (it stays safely on the server so you can sign back in). This is not the same as deleting — signing out leaves your account and its data in place.

You can permanently delete your account and everything tied to it — your topics, cards, chats, review history, and card images — directly in the app: go to Settings → Account → Delete account and confirm. Your account and its associated data are removed from our servers immediately, and the deletion cascades to all of the learning content tied to it. This is irreversible.

One thing does not go, and we would rather say so than let you find out: if someone reported a deck you shared, that report is kept, including the copy of the shared cards it holds. Your account details are unlinked from it, so it no longer points at you, but the report itself remains — otherwise deleting an account would be a way to erase the record of abuse. Nothing else you created survives.

Instructions are also published at https://memori.study/delete-account. If you cannot access the app, email [email protected] from the address on your account and we will process the deletion for you.

Children

Memori is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.

Advertising and sale of data

We do not show third-party ads in Memori, and we do not sell your personal information.

Security

We use reputable providers and standard protections (encrypted transport, authentication, and access controls). No system is perfectly secure, but we work to protect your information and to limit what each provider can see to what it needs.

Changes to this policy

We may update this policy as the app evolves. When we make a material change, we will update the effective date above and, where appropriate, surface the change in the app.
