Who we are

Strato-Altus (“we”, “us”) is a hiking challenge tracker for New England peaks, waterfalls, and trails. The Android app, the web app at app.strato-altus.com, and this site are operated by the Strato-Altus project. Contact: privacy@strato-altus.com.

Information we collect

• Account. When you sign in with Google we receive your Google account ID, email address, and (if provided) display name. Password accounts created by an operator store a username and a hashed password only.
• Profile. Optional display name, bio, home state, profile photo, and visibility preference.
• Hike logs. Places you log, dates, distances, ratings, trailheads, notes, and condition tags you choose.
• Social. Friend codes, friend connections, and community challenge submissions you create.
• Contest photos. Photos you upload to weekly peak or waterfall contests, and votes you cast.
• Purchases. If you buy Premium, we store whether it is active and when it renews or ends. Payment details are handled by Google Play (Android) or by RevenueCat and its payment processor Stripe (web); we never see your card number.
• Technical. Session cookies for signed-in use, approximate IP address for abuse prevention, and standard server logs.

We do not request access to your Google contacts, phone numbers, calendar, or files beyond the ID token used to sign you in.

How we use information

• Provide hike tracking, badges, challenges, friends, and contests.
• Show progress and public profile details according to the visibility you choose.
• Moderate community submissions and enforce rate limits and bans against abuse.
• Operate, secure, and improve the service.

We do not sell your personal information. We do not use your hike data for advertising.

Sharing

Other signed-in hikers may see your username, display name, and content you make visible (for example contest photos or a public profile). Infrastructure is hosted on Cloudflare (Workers, D1, and object storage for photos). Google processes sign-in when you choose “Continue with Google.” If you buy Premium, RevenueCat receives your Strato-Altus account ID to track the subscription across Android and the web, and Google Play or Stripe processes the payment. We do not share your data with other third parties except as required by law or to protect the service and its users.

Retention and deletion

We keep your account and hike data while your account is active. You can delete your account in Settings; that removes your profile, hike logs, friend links, and contest entries associated with the account. Backups and security logs may retain limited records for a short period after deletion.

Children

Strato-Altus is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes

We may update this policy as the product changes. The “Last updated” date at the top will change when we do. Continued use after an update means you accept the revised policy.
