Cookie & Storage Policy

1. Introduction

Cookies are small text files that websites place on your device to store information. Local storage (also called Web Storage) is a similar browser feature that allows web applications to store data directly on your device.

Memento AI does not use traditional browser cookies for its core functionality. Instead, we primarily use your browser's local storage to keep you signed in, remember your preferences, and support offline functionality. This means your data is stored locally on your device and is not transmitted to third-party servers through cookie mechanisms.

This policy explains what data we store on your device, why we store it, and how you can manage or remove it.

2. What We Store Locally

Memento AI uses the following localStorage keys on your device. Each serves a specific purpose required for the application to function correctly.

Session & Authentication

Key Purpose
authUser Your authentication session data. Required to keep you signed in between visits.
consentAccepted A record of your data processing consent, including the date and version you accepted.
pendingInviteCode Temporary storage for a care circle invite code during the login flow. Cleared after use.

Preferences & Navigation

Key Purpose
onboardingComplete Whether you have completed the initial onboarding process, so you are not shown it again.
currentProfileId The ID of the patient profile you are currently viewing or managing.
currentPatientRole Your access level for the current patient (owner, full access, or viewer).
appSettings Your personal preferences, including language, notification settings, and AI response mode.

Cached Data (Offline / Demo Mode)

Key Purpose
patientProfiles Cached patient profile data for offline or demo mode use.
timeline Cached timeline entries for offline or demo mode use.
memories Cached memory photo metadata for offline or demo mode use.
voiceEntries Cached voice recording metadata for offline or demo mode use.
activeUsers Cached care circle member data for offline or demo mode use.

Important: The cached data keys listed above (patientProfiles, timeline, memories, voiceEntries, and activeUsers) are only used when the application is running without a cloud connection, such as in demo mode or during temporary network interruptions. When you are connected to our cloud service, your data is stored securely in our database and is not kept in local storage.

3. Third-Party Storage

In addition to the data Memento AI stores directly, the following third-party services may store limited data on your device:

  • Supabase Authentication — Our authentication provider may store session tokens in your browser's localStorage to maintain your signed-in state securely.
  • Google Fonts CDN — We load fonts from Google's content delivery network. Google may set standard browser cookies for font caching purposes. This is standard browser behavior and is not controlled by Memento AI.

Memento AI does not use:

  • Advertising cookies or tracking pixels
  • Third-party analytics cookies (e.g., Google Analytics)
  • Social media tracking cookies
  • Cross-site tracking mechanisms of any kind

4. How to Manage Your Data

You have full control over the data stored on your device. You can clear all local storage at any time using your browser's built-in tools.

Please note: Clearing local storage will sign you out of Memento AI and reset all your local preferences. You will need to sign in again and reconfigure your settings.

Clearing Local Storage in Chrome

  1. Open Chrome and go to Settings.
  2. Navigate to Privacy and Security.
  3. Select Clear browsing data.
  4. Check the box for "Cookies and other site data" (this also clears local storage).
  5. Choose your preferred time range and click Clear data.

You can also use your browser's Developer Tools (F12) to inspect and selectively remove individual localStorage keys under the Application tab.

Deleting Your Account

If you wish to remove all data stored in our cloud database, you can delete your account through the Settings page within the app. Account deletion removes all cloud-stored data associated with your account, including patient profiles, timeline entries, voice recordings, and memory photos. This action is permanent and cannot be undone.
