Privacy Policy

Last updated: July 8, 2026

This Privacy Policy explains how JumpTree ("we," "us," or "our") handles information in connection with the JumpTree mobile application (the "App"). By using the App, you agree to the practices described here.

The short version

• JumpTree is local-first: your workouts, profile, settings, and impact progress are stored on your device, not on our servers. We do not operate a user account system and never ask for your name or email.
• We use Google Firebase Analytics and Crashlytics to understand usage and fix crashes, and Google AdMob to show ads that help keep the App free and fund reforestation.
• You control ad personalization through your device's tracking settings and the in-app consent prompts, and you can erase all local data at any time from the App's Settings.

Information we collect

Information stored only on your device

The following is created and kept locally on your device and is not transmitted to us: your workout history, your weight (used only on your device to estimate calories — it is never uploaded), unit preference, saved custom workouts, challenge progress, sound settings, and your in-app "droplets"/trees impact totals. A few coarse, non-identifying settings — your fitness level, theme, and language — are also stored locally and, as described below, included as properties in our analytics. If you uninstall the App or use "Reset all data," locally stored information is removed.

Information collected automatically by third-party services

To run, improve, and monetize the App, we rely on Google services that collect data on our behalf:

• Firebase Analytics (Google). Aggregated, pseudonymous usage data — events (e.g., starting or completing a workout, onboarding steps, shares, challenge progress, and ad interactions), device and app information (model, OS version, app version, language), approximate location derived from IP address, and non-identifying user properties (such as your fitness level, theme, language, and ad-frequency preference). We attach a randomly generated, anonymous install ID that is not linked to your real-world identity. We do not send your weight to analytics.
• Firebase Crashlytics (Google). Crash and stability diagnostics (device state, stack traces) so we can fix problems.
• Google AdMob. Serves ads in the App. Depending on your consent and device settings, AdMob may access advertising identifiers (Apple's IDFA / Android's Advertising ID) and ad-interaction data to deliver and measure personalized or non-personalized ads.

How we use information

• Provide and operate the App's features.
• Understand how the App is used and improve it.
• Diagnose crashes and maintain stability.
• Show ads that support the App and fund our reforestation mission.
• Maintain security and comply with legal obligations.

Advertising and your choices

Ads in JumpTree are provided by Google AdMob. You can control how ads use your information:

• iOS (App Tracking Transparency). On first relevant use we ask whether the App may track you across other companies' apps and websites. You can change this anytime in Settings → Privacy & Security → Tracking.
• European Economic Area, UK & Switzerland (GDPR). We present a Google-certified consent message (UMP) before serving personalized ads and let you update your choice later. Declining limits ads to non-personalized.
• United States. Where applicable state laws provide opt-out rights (e.g., "Do Not Sell or Share My Personal Information"), you can exercise them via the in-app privacy options.
• Android. You can reset or delete your Advertising ID in your device settings.

Legal bases (EEA/UK users)

Where the GDPR applies, we process data based on: your consent (for personalized advertising and related identifiers); our legitimate interests (to operate, secure, and improve the App and to show non-personalized ads); and legal obligations. You may withdraw consent at any time through the in-app privacy options or your device settings.

Your rights

Because the App is local-first and does not tie data to your identity, much of your data never leaves your device and can be erased directly:

• Erase your data: use Settings → Reset all data in the App, or uninstall the App, to remove all locally stored information.
• EEA/UK (GDPR): rights to access, rectify, erase, restrict, object, and data portability for any personal data we control.
• California & other US states (CCPA/CPRA and similar): rights to know, delete, correct, and opt out of "sale"/"sharing" of personal information. We do not sell your personal information for money.

To exercise rights involving data held by us, contact us at [email protected]. For data processed by Google, you may also use Google's privacy controls.

Data retention

Locally stored data persists on your device until you reset it or uninstall the App. Analytics and crash data processed by Google are retained according to Google's retention policies.

Sharing and disclosure

We do not sell your personal information. We share data only with the service providers described above (Google Firebase and AdMob) to operate the App, and where required by law. See Google's Privacy Policy.

International data transfers

Our service providers may process data in the United States and other countries. Where required, transfers rely on appropriate safeguards such as Standard Contractual Clauses.

Children's privacy

JumpTree is not directed to children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will address it.

Notifications

The App may ask your permission to send push notifications (for example, optional workout reminders). Granting permission is optional, and you can change it at any time in your device settings. We do not currently send marketing notifications.

Security

We take reasonable measures to protect information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Changes to this policy

We may update this Privacy Policy from time to time. We will revise the "Last updated" date above and, where appropriate, provide additional notice.
