Privacy Policy
Last updated: September 2026
Disclaimer
This text was written by the app's developer (not a legal professional) in the interest of honest transparency about how data is handled. It does not replace a professional legal review, particularly if the app were to be offered more widely to the public.
Who processes your data
Ceou is published independently. For any question about your data, contact contact@ceou.eu.
Data collected
Your email and password (for login), an optional display name and profile picture, and the content you create in the app: homes, rooms, spots, containers, items (name, description, photo, barcode) and their move history.
Hosting
All this data is hosted with Supabase, within the European Union (eu-north-1 region, Stockholm).
AI photo scanning
If you use the photo scan feature to add several items at once, the photo you take is sent to Google's Gemini API (outside the EU) to automatically detect the objects it contains. Google processes this photo only to answer that one-off request. This feature asks for your explicit consent before its very first use, separate from accepting this policy.
The voice assistant
When you talk to Ceou, two services are involved. First your phone's own speech recognition, which turns your voice into text: that is Apple's or Google's depending on the device, and it may send the audio to their servers — the same mechanism as your keyboard's dictation. Then the resulting text, never the audio, is sent to Google's Gemini API, outside the EU, to be interpreted. Your sentence is only processed to answer that one-off request. Like photo scanning, the assistant asks for your explicit consent before its very first use.
Barcode product lookup
If you scan a barcode, that code (no other personal data) is sent to UPCItemDB, a third-party service, to automatically retrieve the product name and photo.
Notifications
If you allow notifications, your phone receives a delivery identifier (a token) issued by Expo's notification service. It is stored with your account so we can alert you — a loan due back, a friend request — and passes through Expo, Apple and Google when a notification is sent, as any phone notification does. It is removed when you turn notifications off or when you delete your account.
Error logs
When the app hits an error, it records the technical message, the error trace and the context of the screen involved, tied to your account. This is used only to fix failures, stays with the same host as the rest of your data, and disappears with your account.
What is never done
Your data is never sold, never used for advertising, and never shared with other app users beyond what you explicitly choose to share.
Retention
Your data is kept for as long as your account exists. You can request its deletion at any time (see below).
Your rights
You can view and edit your data directly in the app at any time. Full deletion of your account and data is done from the app: Profile, then "My account", then "Delete my account". It is immediate and permanent, photos included. For a data export, write to contact@ceou.eu.
Deleting your account and your data
From the app, it is immediate: Profile, then "My account", then "Delete my account". You are asked for your password again, to confirm it is really you.
Without the app, write to contact@ceou.eu from your account’s email address, with "Account deletion" as the subject. Requests are handled within 30 days.
What is deleted: your account and profile, your homes, rooms, spots, containers and items, their photos, their move history, your loans and borrowings, your friends, your shares and invitations, your notification tokens and your error logs.
What remains: homes that friends shared with you are not deleted — they belong to them, you simply lose access. Likewise, if someone recorded lending you an item, that record stays with them: it is part of their data, not yours.
Deletion is permanent: nothing can be recovered from the app afterwards. The host’s technical backups may keep a copy for the length of their rotation, before being overwritten in turn.
