Gradient
Privacy Policy.

1. Information You Provide

During onboarding, Gradient asks for:

• Your name or nickname
• Your email address
• Your phone number (optional)
• The city where you run most
• Your race goal, race distances, and running experience
• Elevation and heat sensitivity preferences

This information is used to personalize your pace plans and, where you provide an email, to send you a copy of your plan and any pace card you request. Your phone number, if given, is used only to send a backup link to your plan in case your phone resets on race day — it is never used for marketing and never shared.

2. Community-Shared Courses

If you choose to share a course with the community library, the following becomes public and visible to anyone using Gradient:

• The course name, location, distance, and elevation profile
• The full route geometry (latitude, longitude and elevation at each point) — including the exact start and finish location
• How you describe the course's origin (an official race route, a route you personally ran, or a route you made yourself)
• Optional race details you choose to add: organiser name, distance category, and race date

Your email address is attached to a shared course privately, as the contact for that listing, so the course can be verified or taken down if needed — it is not displayed publicly. You can remove a course you've shared at any time from the community list.

Because the exact start point of a shared route becomes public, we recommend not sharing a route that starts at your home unless you are comfortable with that location being visible to others.

3. Feedback

If you submit feedback or a message through the app's Help & Feedback screen, we store the message text, the contact details you provide, and the date submitted, so we can read and respond to it.

4. Automatically Collected Information

Gradient uses Firebase to operate:

• Firebase Authentication creates an anonymous device identity, used only to establish ownership of courses you share (so you — and only you — can remove them later). This is not a personal account and requires no sign-up.
• Firebase Analytics collects anonymized usage events (such as which screens are opened or which settings are changed) to help us understand how the app is used and improve it. No personally identifying information is included in these events.
• Firestore, Firebase's database, stores the community course library, your feedback submissions, and account details you provide (email, phone, name, city, goal) under your anonymous device identity.

5. Purchases

If you buy a premium feature (such as an additional color palette) through in-app purchase, that transaction is handled entirely by Apple's App Store / StoreKit. Gradient does not receive or store your payment details.

6. What We Don't Do

Gradient does not sell your personal information. We do not use your data for third-party advertising. We do not share your contact information with anyone other than as described above.

7. Your Choices

• You can use most of Gradient without sharing any course publicly.
• You can remove a shared course at any time from the community library.
• You can reset your profile at any time from Settings, which clears your local goal, preferences, and imported courses.
• You can request that we delete your feedback submissions or account data by contacting us (see below).

8. Data Retention

Your onboarding details are stored for as long as you use the app, or until you reset your profile. Community-shared courses remain public until you remove them or contact us to have them removed.

9. Children

Gradient is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

10. Changes to This Policy

We may update this policy from time to time. Material changes will be reflected by an updated "Last updated" date above.
