Memoria – privacy policy
Last updated: 30 August 2026
In short
Everything you create in Memoria — your recall tables, your associations, your images, your goals and your preferences — stays on your device. Memoria has no user account and no remote database: we cannot read your tables.
The few technical pieces of data that do leave the device are used only to run the app, to understand how it is used, to fix crashes and to display ads. That data is never sold or resold to anyone.
Memoria is developed and published by an independent developer, reachable at florian.duhen.pro@gmail.com (the same address shown on the Settings page of the app).
This policy covers the Memoria mobile app on Android and iOS.
All of your personal usage data stays local. Specifically, the app saves on your phone:
This information is kept in the app’s local storage (SharedPreferences / NSUserDefaults) and in the app’s private container. It is not sent to any server. There is no account, no sign-up and no cloud sync.
If you use the Export feature in Settings, the app writes a JSON file containing your tables to your downloads folder or to the app’s documents folder. That file is yours: you alone decide whether to keep it, share it or delete it.
The app records anonymous usage events to understand which features are used: starting a training session, creating an association, opening settings, viewing the Premium page, and so on. These events contain neither the content of your tables, nor the names of your associations, nor your images.
Firebase Analytics links these events to an installation identifier generated by Google, along with technical information (device model, OS version, language, approximate country). The app records a single user property: whether or not you are a Premium user.

When the app crashes, a crash report is sent automatically: the nature of the error, the stack trace, the device model and the OS version. These reports are used only to fix bugs. They do not contain the content of your tables.

The free version of Memoria displays ads:
To serve these ads, the Google Mobile Ads SDK uses your device’s advertising identifier (Advertising ID on Android, IDFA on iOS) along with technical and approximate location information. Memoria also passes the SDK a fixed list of topical keywords (memory, brain training, mnemonics, and so on) so that the ads stay relevant to what the app is about. These keywords are the same for everyone and do not describe your behaviour.
Your consent. If you are in the European Economic Area, the United Kingdom or Switzerland, a consent form provided by the Google User Messaging Platform (UMP) is shown on first launch. Your choice is stored and honoured by the ads SDK. You can change that choice at any time from the app’s Settings, under “Manage my ad consent”.
On iOS. Once the app is open, iOS asks you, through App Tracking Transparency, whether you allow Memoria to track your activity for ad personalisation. If you decline, the advertising identifier is not available and the ads you see are not personalised. Declining has no effect on how the app works.

The Premium purchase is a one-off payment, handled entirely by your platform’s store: Google Play Billing on Android, Apple StoreKit / the App Store on iOS.
Memoria never sees your payment details: not your card number, not your address, not your Google or Apple account identifier. The app only receives a confirmation from the store that the “premium” product has been bought or restored, and saves a yes/no flag locally.
The “Restore my purchases” entry on the Premium page asks the store to find a purchase already made with the same account. You trigger it yourself; it never runs automatically at launch.

When you search for an image to illustrate an association, Memoria sends the search term you typed and the app’s language to the Pexels stock image API, in order to get a list of results back. No identifier relating to you is transmitted: no device identifier, no advertising identifier, and none of your table content.
As with any network request, your device’s IP address is visible to Pexels and to its hosting provider. The thumbnails you see are downloaded from Pexels’ servers.

Memoria uses local notifications only: they are scheduled by the app on your device to remind you to train or to let you know that a new goal is available. No remote push notification is sent from any server, and no notification token is transmitted.
You can turn notifications off at any time from the app’s Settings or from your device’s system settings.
Under the GDPR, you have the right to access, rectify, erase, restrict and object to the processing of your data, as well as the right to data portability.
In practice, since Memoria holds no data about you on its own servers, you exercise these rights directly from the app:
For data held by Google or Pexels, you can also exercise your rights directly with those companies through the links above. For any question, write to us at florian.duhen.pro@gmail.com; we reply within one month. You also have the right to lodge a complaint with your data protection authority (in France, the CNIL).
Memoria is not intended for children under 13 and does not knowingly collect data from minors. The app never asks for a name, an email address, an age or any other identifying information. If you believe a child has provided personal data through the app, contact us and we will take the necessary steps.
This policy may change as the app changes. The last-updated date shown at the top of this page is authoritative. Any significant change will be mentioned in the app’s release notes.
