Email contact@penguinfalls.com with “Sightlines” in the subject. Include your iPhone model, iOS version, app version, and what happened. Do not send passwords, payment card details, or precise location. Remove private details from screenshots first.

Location and compass

Allow location while using Sightlines in iPhone Settings. Precise Location improves nearby results. If the heading is unstable, move away from magnets, cars, and other metal and recalibrate the compass. An address candidate is not proof of the source of a light, sound, or event.

Failed or empty scans

Check your connection, try a wider cone, or increase the distance. Nearby and Night cloud scans require internet; map tiles also depend on connectivity. Offline World Line uses bundled geographic data. Failed or empty scans do not consume the three free scans or the annual 100-scan allowance. If scans are temporarily busy or paused, retry later; do not purchase again to fix a connection problem.

Your allowance

You get three successful cloud scans before purchase. Plus is $19.99/year in the U.S. and includes 100 fresh cloud scans per subscription year. Nearby and Night share that allowance. Settings shows remaining scans and the current period end. Unused scans do not roll over. Saved history and offline World Line stay available after your allowance is used or your subscription expires.

Restore, manage, or cancel

Use the same Apple Account that purchased Plus, then choose Restore Purchases in Sightlines Settings or on the subscription screen. A restore does not reset the annual counter. If a purchase is pending, wait for Apple approval; do not buy again to troubleshoot.

Manage Subscription in Settings opens Apple subscription settings. Cancel at least 24 hours before the current period ends to avoid renewal. Deleting the app or guest account does not cancel billing. Apple handles refund requests at Report a Problem.

History and account deletion

Completed results are automatically saved on this device. Open History to read, copy, share, favorite, or delete them; Settings can delete all history. There is no cloud history sync. If device storage is unavailable, a save warning offers a retry; copy or share the displayed result before closing it.

The app uses a guest account, not an email/password sign-in. “Delete guest account” in Settings removes its server identity, user ledger, RevenueCat customer record, and local history/session. Subscription-period usage is retained separately to prevent the same purchase receiving another 100 scans after deletion. You must explicitly create a new guest account before scanning again. See the privacy policy for retention details.
