Grand Archive – Privacy Policy

Last updated: October 31, 2026

Grand Archive is a personal film-catalogue app for Android. This policy explains what the app does with

your information.

What the app stores

Your films, wishlist, viewing diary (dates, ratings, attention level and notes), barcodes you link to films,

and cover photos you take are stored only on your phone, in the app's private storage. Android's cloud

backup is turned off for the app. The developer has no server and never receives this information.

When the app goes online

The app connects to the internet only when you ask it to:

- Film lookups: when you search for a title, paste an ID, refresh a film's details, or ask for similar

films, the app sends that search text or ID to Wikipedia and Wikidata (Wikimedia Foundation) and downloads

the film's details and poster. Your collection is not sent.

- Google Sheet backup (optional): if you connect a Google account, the app creates one spreadsheet named

"Grand Archive" in your Google Drive and keeps it up to date with your films, wishlist and viewing diary,

including diary notes. The app requests only the "drive.file" permission, which lets it see and edit only

files it created. It cannot see any other files in your Drive. The spreadsheet belongs to you, in your

account, under Google's privacy policy.

An Offline switch in the app stops all of the above.

Things the app never does

It doesn't collect analytics, show ads, track your location, or share or sell information to anyone.

Barcodes and photos are processed on the phone and never uploaded.

Google user data

Data obtained through Google APIs is used only to keep your own spreadsheet up to date, as described above.

It is not transferred to anyone else, not used for advertising, and not read by humans. Grand Archive's use

of information received from Google APIs adheres to the Google API Services User Data Policy, including the

Limited Use requirements.

Your control

You can disconnect the Google Sheet in the app at any time, remove the app's access at

myaccount.google.com/permissions, delete the spreadsheet from your Drive, or delete the app to remove all

data stored on the phone.
