English summary

ranu processes photos and journals on your phone; our servers do not receive original photos or full routes. Apple system geocoding receives coordinates to look up place names and time zones. Map and public-sign requests omit ranu device identity but send roughly 5 km cell IDs and normal network metadata, including IP addresses. Map services supply the base map. iCloud Photos follows your Apple settings.

Authenticated requests send a random device secret over TLS; the server stores its digest, optional name, connections and invites. When you choose to leave a sign, its coordinates, date and pictogram are uploaded with that identity. You may choose one fixed preset reminder and a 7, 30 or 90 day lifetime; free-form text is not accepted. After 24 hours it becomes public, with rounded coordinates, the photo month only and no author identity, photos or full route. The reminder and lifetime are public too; expiry is rounded up to a UTC date boundary, without an exact publication time. New signs count their lifetime from publication. Expired signs are no longer public and cannot receive new stamps or passes; their owner can still read existing counts and remove them. Legacy pictograms do not automatically expire. The stranger-sign setting is off by default; enabling it can query signs without connected friends. Turning it off does not make your own published signs private. You can remove your signs. Stamp and pass requests omit device identity and carry sign IDs and deduplication tokens; network metadata still reaches the service.

If a save result is uncertain, the app can send an authenticated request ID to close that attempt and recover its result, without resending locations or reminder content. The server retains closed request IDs with the device-identity digest to prevent late requests from creating signs again. These recovery markers contain no location or reminder content and are not public.

You choose where to share cards or save exports and backups. Cards can include photos and places; exports contain locations. Journal backups contain edits and references, not original photos, device secrets or friend settings. Deleting the app does not delete system-library photos, saved cards, exports, backups or server records; the device secret may remain in the system Keychain. Remove signs and disconnect friends in the app, or contact developer@nateguco.com about server data. Usage counts and notifications stay local. No ads or third-party analytics.
