Privacy Policy

Effective date: May 7, 2026  ·  Frontier Forge LLC

ArrowForge ("we", "our", or "us") is developed and operated by Frontier Forge LLC. This Privacy Policy explains what information we collect, how we use it, who we share it with, and what choices you have — including how to delete your account and data.

ArrowForge is designed as a local-first app. The core app is fully functional without an account. An optional account unlocks cloud backup and future Pro features. We collect only what is necessary to provide those services.

1. What information we collect

Without an account (default)

ArrowForge runs entirely on-device with no account required. In this mode:

No account information, no email address, and no personal identifiers are collected when you use ArrowForge without signing in.

With an optional account

If you choose to create an account, we collect:

Sign in with Apple

If you choose Sign in with Apple, Apple authenticates you and may share:

We receive only what Apple sends. Apple's identity token is verified server-side; we do not receive your Apple ID password or any payment information. Apple's data practices are governed by the Apple Privacy Policy.

What we never collect

2. How we use your information

We use the information we collect only to:

We do not use your information for advertising, profiling, or sale to third parties — ever.

3. Third-party services

ArrowForge uses a small number of carefully chosen third-party services. We share only the minimum data each service requires.

Nominatim / OpenStreetMap

Used for geocoding when you search for a training location or destination by name. We send your search query and, if you tap "Use my location," your approximate device coordinates. Governed by the OSM Foundation Privacy Policy. No account data is sent to this service.

Open-Elevation

Used to look up elevation (metres above sea level) for a selected coordinate. We send only the latitude and longitude of the chosen location. No account or personal data is sent. Requests are triggered by your explicit location selection.

Supabase

Supabase provides authentication (sign-up, sign-in, password reset, Apple Sign In verification) and cloud database storage for accounts. When you create an account, your email address, hashed password, and build data are stored on Supabase-managed infrastructure hosted on Amazon Web Services (AWS) in us-east-2 (Ohio, USA). Supabase acts as a data processor on our behalf and is bound by a Data Processing Agreement. Governed by the Supabase Privacy Policy.

Apple (Sign in with Apple)

If you use Sign in with Apple, Apple authenticates your identity and passes a verified credential to our server. Apple may share your name and email address per your iOS privacy settings. We do not share any ArrowForge data back to Apple beyond standard App Store analytics that Apple collects from all apps. Governed by the Apple Privacy Policy.

No other third-party network requests are made by the app.

All ballistics calculations run entirely on-device. No usage analytics, crash reporters, ad networks, or social SDKs are embedded in ArrowForge.

4. Data storage and security

On-device data

Build data for users without an account is stored in AsyncStorage on your device. It is not encrypted at the application layer but is protected by iOS device encryption (when your device passcode is enabled). Uninstalling the app permanently removes all locally stored data.

Account data

Account credentials (email and hashed password) and synced build data are stored on Supabase's PostgreSQL database hosted on AWS us-east-2. Data is encrypted in transit (TLS 1.2+) and at rest. Authentication session tokens are stored in your device's iOS Keychain via expo-secure-store, which provides hardware-backed secure storage.

What we do not do

5. Data retention

We retain your data for as long as your account is active or as needed to provide the service. Specific retention periods:

6. Account and data deletion

To delete your account and all associated data: email arrowforgeapp@tuta.io with the subject line "Delete my account". Include the email address associated with your account. We will permanently delete your account and all server-side data within 30 days and confirm by reply.

Account deletion removes:

Deletion does not remove data stored locally on your device. To remove local data, delete the app from your device.

Note: if you signed in with Apple, revoking ArrowForge's access through your Apple ID settings (Settings → Apple ID → Password & Security → Apps Using Apple ID) will sign you out. To also delete your ArrowForge account data, email us as described above.

7. Your rights

Depending on where you live, you may have rights regarding your personal data, including:

To exercise any of these rights, email arrowforgeapp@tuta.io. We will respond within 30 days. We do not charge a fee for reasonable requests.

California residents: under the CCPA, you have the right to know what personal information is collected, to delete it, and to opt out of sale. We do not sell personal information.

8. Children's privacy

ArrowForge is not directed at children under 13 years of age, and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has created an account, please email arrowforgeapp@tuta.io and we will delete the account promptly.

9. Changes to this policy

We may update this Privacy Policy as the app evolves — for example, when we add new features, integrations, or subscription tiers. When we make material changes, we will update the effective date at the top of this page and, where appropriate, notify signed-in users within the app. Continued use of ArrowForge after changes take effect constitutes acceptance of the updated policy.

The previous version of this policy (effective May 6, 2026) is available on request.
