What's new in this version

Version 2.1.0 — 5 September 2026.

• The app is now rated 16+, and we check. On iOS your age category comes from Apple as a broad range — never your birthdate. Where the store gives no signal, the app asks you to confirm you are 16 or older and keeps that as a single yes/no flag on your device. No age data of any kind reaches our servers. Section 2.A also now says which two on-device values survive uninstalling and account deletion. → Sections 2.A, 2.G and 12
• Accounts unused for 365 days are now deleted automatically, with a notification 7 days beforehand. Opening the app resets the clock, and active subscribers are never deleted. Previously we kept accounts for the lifetime of the service. → Sections 2.E and 7
• More information of what happens to your photograph. The picture is the entire content of what we send to Google Gemini; your collection, notes and identifiers never leave your device.
• New articles on home page: all the written reference content is AI-generated too — the field guide, the articles, the Real vs Fake comparisons, and the zodiac and birthstone pages. → Sections 2.C and 14
• Other changes. Sections 2.G and 12 have been rewritten — same practices, said more plainly: what the store tells us and what it cannot, which answer wins where they disagree, what happens while a guardian's decision is outstanding, and the legal basis for each. → Sections 2.G and 12
• Various clarifications: Our backend is in Supabase's eu-west-1 region in Ireland. Section 2.B now lists its datasets including your credit balance, the date you last opened the app, consent-withdrawal notices (which we verify and discard without recording), and the IP address any server unavoidably receives. There is still no analytics SDK in the app: iOS install attribution runs inside the operating system with no data from us. → Sections 2.B, 2.F and 5
