Privacy Policy

Global Historical Timeline — last updated August 2026

Short version: this app doesn't have accounts, doesn't collect personal data, and doesn't send your timeline edits anywhere. Everything you add or change stays on your device unless you explicitly choose to export and share a file yourself.

What this app does

Global Historical Timeline is a browsable historical timeline. The dataset is built into the app — no server lookup is needed to view it. You can add your own entries, edit existing ones, and delete entries; these personal changes are kept in the app while it's open.

What we don't collect

We don't ask you to create an account or sign in. We don't collect your name, email address, location, device identifiers, or any other personal information. We don't use analytics, advertising, or crash-reporting services, and the app doesn't request any special device permissions.

What stays on your device

Personal timeline edits (entries you add, change, or remove) live in the app's memory while it's running. They are not saved automatically and are not sent to any server.
Export / Import lets you save your personal edits to a file and load them back in later, or on another device. That file is created and handled entirely by you — through Android's own "share" or "save" screen — and never passes through us or any service we operate.
Display preferences — currently just any custom region colors you set — are saved locally on your device (using standard on-device browser storage) so they persist between sessions. This never leaves your device.

Third-party services

The app loads its typeface (Inter, from Google Fonts) over the network when you have an internet connection. Loading any web resource necessarily shares your device's IP address with the server providing it — in this case, Google. We don't control or see this data ourselves; see Google's Privacy Policy for how Google handles it. No other third-party service is used by this app.

Children's privacy

This app doesn't knowingly collect information from anyone, including children, because it doesn't collect personal information from anyone at all.

Changes to this policy

If this app's data practices ever change, this page will be updated and the "last updated" date above will reflect that.
