Screen Time and challenge data

• No LEAST account is required.
• Apple's isolated Device Activity report extension processes app activity on your current iPhone to calculate LEAST's rank, progress, daily result, and streak.
• Website activity is excluded from the LEAST ranking.
• Per-app Screen Time data is not sent to Blue Snake or exposed to the host app.

Data stored on your device

• The shared app container holds only LEAST's opaque self-selection, the first challenge day, your resolved app language, your visual theme, and whether Apple has verified a Trophy entitlement.
• The isolated report extension privately retains finalized dates with won or lost outcomes so a later Trophy purchase can reveal the complete calendar. It does not keep durations, ranks, app identities, or tokens in that archive.
• Reminder preferences, LEAST's current-day foreground duration, and one-shot presentation state stay locally on your iPhone. Blue Snake does not receive this data.

Optional local reminders

• LEAST asks for notification access only after challenge setup and only after you explicitly opt in on a contextual explanation screen.
• LEAST can schedule at most two local reminders per day: a new-day reminder at 08:00 and an afternoon boost at a time you choose. You can turn either reminder off separately.
• The afternoon boost uses only whether LEAST itself has been in the foreground for less than 15 minutes that day. It does not use Screen Time, your rank, the leading app, or app names.
• Reminder settings, notification content, and the foreground counter are processed on your iPhone and are never uploaded to Blue Snake.

LEAST Trophy purchases

LEAST Trophy is an optional non-consumable In-App Purchase. Apple processes the purchase, payment, storefront price, and restoration. LEAST uses StoreKit to verify access to the archive and cosmetic extras; purchasing never changes Screen Time permission, ranking, dots, streaks, or challenge completion.

Tracking, analytics, advertising, and sale

LEAST contains no advertising SDK, analytics SDK, cross-app tracking, or data sale. This microsite currently uses no analytics or advertising cookies and no website tracking.

Microsite and support data

Site hosting may process technical request information needed to deliver and secure the site, such as IP address, browser or device information, requested page, and timestamp. If you contact support, Blue Snake processes the details you provide to answer your request and meet applicable legal obligations.

Your choices and rights

You can disable either reminder in LEAST, revoke Screen Time or notification access in iPhone Settings, and remove local app data by deleting LEAST. Deleting the app also removes its local settings and archive; an App Store purchase can be restored later, but deleted local history cannot. Where applicable, you may request access, correction, deletion, restriction, or object to processing by emailing least@bluesnake.nl. You may also complain to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
