Privacy Policy

Last updated: 26 July 2026

uMaps ("we", "the app") is a community map for documenting urban-exploration sites. This policy explains what we collect, why, and the choices you have. We collect the minimum needed to run the app and never sell your data.

What we collect

Account — the email address and username you sign up with, used to authenticate you and attribute your contributions.
Content you submit — spots you document (including the exact coordinates you enter), reviews, visit logs, saved lists, and photos you upload. Uploaded photos are re-encoded on your device to strip embedded GPS/EXIF metadata before they leave your phone.
Location — if you grant permission, your device location is used to center the map and to help you place a spot you are documenting. Your live location is not stored on our servers or shared with other users.
Subscription status — if you buy uMaps Pro, our payments provider (RevenueCat) and Apple process the transaction and tell us whether your subscription is active. We never receive your card details.
Basic diagnostics — standard technical logs (e.g. error reports) needed to keep the service reliable.
Advertising measurement — uMaps is advertised on Meta (Facebook and Instagram), and the app includes the Meta SDK so we can tell that an install or a subscription came from one of those ads. iOS asks for your permission first (the App Tracking Transparency prompt). Only if you allow tracking is your device advertising identifier (IDFA) sent to Meta Platforms, Inc. together with a small set of app events: install, account registration, your first documented spot, trial start, and subscription. If you decline, the identifier is not sent; Meta may still receive aggregate, privacy-preserving attribution signals through Apple's SKAdNetwork and aggregated event measurement.

The location-privacy model

Public map pins are deliberately approximate: every spot's published location is offset by a stable random distance within a fuzz radius. Exact coordinates and access notes are shown only to members who have earned access — through community reputation or contribution-earned keys — or to a spot's own author. This is a core safety feature, not a paid one: keys are never sold, and Pro never unlocks exact locations.

How we use it

To operate your account, show and attribute community content, provide map and submission features, process subscriptions, keep the service secure, and measure how our own advertising performs. The advertising data described above is used only to measure and improve those ads — uMaps shows no ads inside the app, and we do not sell your data.

Who we share it with

Service providers who run the app on our behalf: Supabase (database, authentication, photo storage), RevenueCat and Apple (subscription processing), and Meta Platforms, Inc. (advertising measurement — the app events listed above, plus the advertising identifier only if you allowed tracking; see Meta's privacy policy). Content you publish (spots, reviews, logs, photos, username) is visible to other users by design. We may disclose information if required by law.

Retention & deletion

We keep your data while your account is active. You can delete your account in-app (Profile → Delete account) or by emailing us at the address below; we will action email requests within 30 days. Note that community contributions may be retained in anonymized form to preserve the integrity of the shared record.

Your choices

Revoke location access anytime in iOS Settings.
Allow or refuse ad tracking when iOS asks, and change that answer later in iOS Settings → Privacy & Security → Tracking.
Manage or cancel your subscription in the App Store.
Request access to, or deletion of, your data by email.

Children

uMaps is not directed to children under 13, and we do not knowingly collect their data.

uMaps documents existing sites and does not encourage unlawful entry. Access notes lead with legal routes — tours, permits, and open-to-the-public hours.
