Privacy policy
Mnemesia asks you for an account, to give you the content of your faculty and your ronéo. Your courses, cards and multiple-choice questions stay on your devices and in your iCloud: they only go through our servers if you turn on “Sync my devices”.
Last updated: November 14, 2026
In short
This is an English translation provided for convenience; the French version prevails.
- The content of your courses stays on your devices, or in your own iCloud if you turn it on. It only goes through our servers if you turn on “Sync my devices”, to find it on an Android, a PC or another Apple ID.
- Your account holds very little: your email address, an encrypted password, your year, your faculty and your connected devices.
- Nothing is sold, nothing is used for advertising, no trackers.
- You delete your account yourself, from the app.
Who is responsible for your data
Mnemesia SAS, 47 rue Vivienne, 75002 Paris, France, publisher of the app and of this site (see the legal notice). For any question: contact@mnemesia.com.
What your account contains
- Your email address, university or personal, and a backup address if you add one. It is used to sign you in, to send you verification codes and to know which faculty you belong to.
- Your password, stored encrypted: no one can read it, not even us.
- Your year of study, your faculty and your ronéo, if you are a member: they decide which content is offered to you.
- Your connected devices: their type (iPad, iPhone, Mac, Windows computer…), the version of Mnemesia and the date of the last connection, without the name you gave them. You see them in Settings > Account, and you can sign them out.
- Your choices: the kinds of content you agreed to receive, and the ones you declined, so they are not offered again.
This information is used only to run your account: signing you in, giving you access to the content meant for you, and protecting the account. For that last point, the server limits sign-in attempts: it uses the IP address for this, on the spot, without storing it in our database. Like any host, Render and Vercel keep technical connection logs for a few days, IP address included, for the security of their servers.
What we do not see
As long as you do not turn on “Sync my devices”, your course handouts, annotations, cards, multiple-choice questions, answers, progress and planner stay in your Mnemesia folder, on your devices. Content sent by your faculty or your ronéo arrives in that folder and stays there. The server only knows that a piece of content was offered to you, and whether you declined it.
The app contains no advertising, no trackers and no measurement tool from another company.
Sync my devices, if you turn it on
This setting lets you find your work on a device iCloud does not link: an Android phone, a PC, or an Apple device signed in to another Apple ID. Once it is on, Mnemesia sends through its servers your courses (PDF files), your cards and multiple-choice questions, your progress, your annotations, your planner and how your subjects are organized.
- Who can access it: your devices signed in to your account, and no one else. Mnemesia does not read this content, does not analyze it and does not share it with anyone. It is encrypted in transit and on our hosts’ disks, but not end to end.
- Shared files: an identical file (for example a handout distributed by your ronéo) is stored only once, even if several students have it. Only accounts that have it on one of their own devices can download it.
- Limit: 2 GB of personal courses per account. Beyond that, new courses stay on your device.
- How long: as long as your account exists. A file no device uses any more is erased 30 days later. If you delete your account, or after 3 years without signing in, everything that was synced is erased from our servers within 30 days.
- Turning it off: at any time, in Settings. Nothing more is sent, but what was already sent stays on our servers: to erase it, delete your account or write to us.
Statistics
Today, the app sends no usage statistics. We only see what an account implies: how many accounts exist, and when each device last connected.
If Mnemesia ever measures how the app is used (time spent, features used), it will be in totals only, never the content of your courses, kept 13 months at most, with a setting to refuse. It will be written here first, and announced in the app before being turned on.
Who has access
The Mnemesia team, to manage accounts; it does not open the content you sync. Your faculty, if it has access to our console, only sees totals about its students (for example the number of accounts), never an individual. Your ronéo sends us the email addresses of its members so we can open its content to you. No information is sold or shared for advertising.
How long
- Your account: until you delete it, or after 3 years without any connection. In that case, an email warns you one month before: signing in again is enough to keep it.
- A connection on a device: 180 days without use, then you need to sign in again.
- A verification code: 15 minutes, and a sign-up started but not finished is erased a month later.
When you delete your account (Settings > Account), the server erases your account, your addresses, your devices and your connections. It only keeps a record that a deletion took place, and the reason if you chose one (it is optional), with nothing that identifies you. Database backups erase it in turn at the end of their retention period. Your Mnemesia folder stays on your devices: it is yours.
Where this information is hosted
- The account server: Render, Frankfurt region, European Union.
- The database: Neon, Frankfurt region, European Union.
- Content sent by faculties and ronéos, and what you sync: Cloudflare R2, stored in the European Union.
- Emails (verification codes): Brevo, a French company.
- This site: Vercel.
On your devices
On a computer, the Mnemesia folder is the one you choose. On iPad and iPhone, the Filesapp shows it under “On My iPad > Mnemesia” (or “On My iPhone”). On Android, the Files app shows it too. Your handouts and notes are real files there.
On iPad, iPhone and Android, uninstalling the app erases this folder with it: this is a rule of the system. Copy it first if you want to keep it.
iCloud, if you turn it on
On Mac, iPad and iPhone, a setting stores the Mnemesia folder in your own iCloud, so you find your courses from one device to another. The transfer is done by Apple, in your iCloud space: no Mnemesia server sees your courses, unless you also turn on “Sync my devices”.
Apple Calendar, if you allow it
Mnemesia can show your calendars in its planner and add your study sessions to them. It asks first, through the system prompt, and you can withdraw this access at any time. These events stay in the Calendar app of your device.
This site
You read this site and download Mnemesia without signing up and without tracking cookies. To count downloads, the site records each click on a download button: the chosen system, the date, the country and the approximate city, with no name, no IP address, no cookie and no identifier.
Before September 26, 2026, downloading required signing up (first name, last name, email address, phone, faculty and year), and an older version of the app had accounts. These sign-ups and these old accounts have been erased.
App stores
Apple, Google and Microsoft measure downloads from their store and give us the total, without naming anyone. To tell you about a new version, the app asks the store for the latest version of Mnemesia, without sending anything about you.
Your rights
You can access, correct, export or erase the information about you, and object to its use. The simplest way: delete your account from the app. For everything else, one address: contact@mnemesia.com. We reply within one month.
If you disagree, you can contact the French data protection authority (CNIL), cnil.fr.
Changes
Any change to this policy is published on this page, with its date. Any new collection would be written here first, and announced in the app before being turned on.
