Privacy

Last updated: July 2026

Glotalot has no ads and no third-party trackers. Your progress and a small set of anonymous usage events go only to Glotalot’s own servers. We don’t sell, share, or rent them to anyone.

What we don’t do

• No third-party analytics or advertising SDKs.
• No tracking cookies, fingerprinting, or cross-site tracking.
• No selling or sharing of data with anyone.
• No account, name, or email required to play.

What we do store

• On your device (browser localStorage): your vocabulary estimate, training progress, streak and XP. Clearing your browser data — or using “Start over” in the app — erases it.
• On our own servers: so your progress survives across devices and browser clears, we keep a copy tied to an anonymous id (a random token in a first-party cookie — never your identity). Nothing here is personally identifying.
• Anonymous word statistics: which words are answered correctly or not, aggregated across everyone, so the test difficulty calibrates itself. These are counts per word, not tied to any person.
• Anonymous usage counts: events such as starting or completing a test, finishing a deck, or sharing a score. These are tied only to the same anonymous session used for progress sync and help us measure whether the game is useful.

Cookies

One first-party cookie holds an anonymous session token so your progress can sync. It is not used for tracking or advertising, and it never leaves Glotalot. We don’t fingerprint your browser or add a separate analytics identifier.

Changes

If we ever add optional accounts (e.g. sign-in to sync across devices), we’ll update this page and it will remain opt-in. The promise of no third-party tracking or advertising is not going to change.
