iOS App Privacy Policy

Effective date: August 19, 2026. Last updated: August 20, 2026.

This Privacy Policy explains how Big Much LLC ("Good Dopamine," "we," "us," or "our") collects, uses, and protects information in connection with the Good Dopamine iOS application (the "App").

This policy covers the iOS app only. Our separate Website Privacy Policy covers good-dopamine.app and any information collected when you visit it. Where the two differ, this policy controls for anything you do inside the App.

We built Good Dopamine around a simple principle: the data that reveals the most about you — which apps you use, when you reach for your phone, how you feel — should stay on your device. We operate no servers of our own and store none of your personal content. This policy describes exactly what stays local, what limited information leaves your device, and what happens to it.

1. The short version

• Your Screen Time data never leaves your device. We cannot see which apps you have installed or which apps you block. Apple's frameworks make this technically impossible for us.
• Your check-ins, reflections, notes, and personal answers are not sent to any server we operate, and are not included in analytics. We have no backend and no account system. We never see the content of what you write or record in the App.
• We collect limited, anonymous usage analytics through Mixpanel so we can find bugs and understand which features are useful. It is not tied to your identity, does not include your content, and is the only category of information that leaves your device. You can turn it off in the App at any time (Customize → Anonymous Analytics). Section 2.4 describes it in full.
• We do not sell your data or share it for advertising. There are no advertising SDKs in the App.
• You can delete everything by removing the App from your device at any time.

The sections below give the full detail. If anything here conflicts with the summary above, the detailed sections control.

2. Information we collect

2.1 Screen Time and app blocking data (never leaves your device)

Good Dopamine uses Apple's Family Controls, ManagedSettings, and DeviceActivity frameworks (collectively, the "Screen Time API") to let you block distracting apps and see usage trends.

Apple designed these frameworks so that developers never receive readable information about your apps. When you choose apps or categories to block, iOS gives the App opaque tokens — encrypted references that only Apple's own frameworks can interpret. We cannot resolve these tokens into app names, and we cannot enumerate the apps installed on your device.

Specifically:

• Screen Time authorization is requested through the iOS system prompt and is granted only by you.
• Your app and category selections, blocking schedules, and shield settings are stored locally on your device.
• Usage measurements produced by the DeviceActivity framework are processed inside an on-device app extension. They are never transmitted off your device.
• We do not sell, rent, use for advertising, or disclose to any third party any data obtained through the Screen Time API, for any purpose. This is a commitment we make to you and to Apple.

You can revoke Screen Time access at any time in Settings → Screen Time, or by removing the App. Some features will not function without it.

2.2 Wellness and activity data (never leaves your device)

The App stores information you create as you use it, including:

• Activities you log, complete, or skip (for example movement, breathwork, time outdoors, learning, creating, connecting)
• Custom activities and pinned favorites you define
• Baseline check-in responses, mood or energy ratings, and weekly reflection answers
• Streaks, scores, and trend history derived from the above
• Your onboarding responses and app preferences

This information is stored only in the App's local database on your device. We do not operate a server, we do not sync this data through iCloud, and we never receive your check-in responses, reflection answers, notes, the free-text names of custom activities you create, or the numeric baseline score we compute for you. We do receive limited anonymous signals about how the App is used — for example, that a standard activity in a given category was completed — as described in Section 2.4. These are not tied to your identity and never include the content you write. If you delete the App, this data is deleted with it and cannot be recovered by you or by us.

2.3 Health data

The App does not read from or write to Apple Health (HealthKit), and it does not collect step counts, heart rate, or any other sensor-based health measurement.

2.4 Product analytics and diagnostics

To find bugs and understand which parts of the App people use, the App sends limited, anonymous analytics events to Mixpanel, Inc., a third-party analytics provider. This is the only information that leaves your device. It is designed to describe how the App is used in aggregate — not to build a record of what you personally recorded in it.

What we send:

• Usage data — which screens you view, how far you get through onboarding, session starts and lengths, and similar in-app events, so we can see which flows work and where people get stuck.
• Standard activity completions — when you complete one of the App's built-in activities, we log its name and category (for example "movement") so we can understand which activities are popular. Activities you create yourself are logged only as "custom" — the name you typed is never sent.
• Aggregate counts — for example, how many restorative versus cheap-dopamine activities you logged during onboarding, or how many apps or categories you chose to block. These are counts only, never the specific items.
• A coarse baseline category — a single interpretation label (for example "balanced"). We never send the underlying numeric baseline score.
• Diagnostics — crash and error events, and basic performance data.
• Identifiers — a randomly generated installation identifier used to group events from the same device. This is not the IDFA, is not shared with advertisers, and is reset if you delete and reinstall the App.
• Device and environment data — device model, operating system version, app version, and locale.

We have disabled IP-based geolocation in our analytics, so Mixpanel does not infer your city or region from your connection, and the App does not request location permission.

What we do not send: the free text of your reflections, notes, or messages; the names of custom activities you create; your numeric baseline score; the motivations, aspirations, or phone-use estimate you enter during onboarding; and your Screen Time selections (which are opaque even to us). We do not use session replay or any screen-recording technology.

Your choice: You can turn analytics off at any time in the App under Customize → Anonymous Analytics. In the EEA and UK, analytics is off by default and is only collected if you opt in; everywhere else it is on by default and you can opt out at the same control. You can also stop all collection immediately by deleting the App, or email team@good-dopamine.app to request deletion of analytics data associated with your installation identifier, and we will process the request within 30 days.

Apple may separately provide us with aggregated crash and performance data if you have opted in to share analytics with app developers in Settings → Privacy & Security → Analytics & Improvements. This data is aggregated by Apple and does not identify you.

2.5 Purchases and subscriptions

If you purchase a subscription, the transaction is handled entirely by Apple through In-App Purchase. Subscription status is validated on your device against your Apple Account. We never receive or store your payment card number, billing address, or Apple Account credentials, and we do not maintain any record of your purchase on our systems.

2.6 Support correspondence

If you email us, we receive your email address and whatever you choose to include in your message. We use it only to respond to you, and we retain it for up to 24 months.

2.7 What we do not collect

We do not collect your name, precise location, contacts, photos, microphone or camera input, browsing history, biometric data, or the Advertising Identifier (IDFA). The App contains no third-party advertising SDKs and does not track you across other companies' apps or websites.

3. How we use information

We use the limited information described above to:

• Operate the App's features on your device
• Display your trends, streaks, and baseline history back to you
• Diagnose crashes and fix bugs
• Understand which features are useful so we can improve the App
• Provide customer support
• Comply with legal obligations

We do not use your information to build advertising profiles, to sell to data brokers, to train third-party advertising models, or to make automated decisions that produce legal or similarly significant effects about you.

4. How we share information

We do not sell your personal information, and we do not share it for cross-context behavioral advertising.

We share limited information only with:

Mixpanel acts as our service provider and is contractually restricted to using this data only to provide analytics services to us.

We may also disclose information if required by law, subpoena, or valid legal process, or to protect the rights, safety, or property of our users, the public, or us. If we are ever involved in a merger, acquisition, or sale of assets, information may be transferred, and we will notify you before your information becomes subject to a different privacy policy.

Under no circumstance do we disclose Screen Time API data, activity logs, or check-in content to any third party. We do not possess it.

5. Data retention

• On-device data (Screen Time settings, activity logs, check-ins, reflections) stays on your device until you delete it in the App or delete the App. We have no copy.
• Analytics events are retained by Mixpanel for up to 12 months and then deleted.
• Support emails are retained for up to 24 months.

6. Your choices and rights

Regardless of where you live, you can:

• Delete your on-device data — delete the App from your device, which permanently removes all data stored locally. (A dedicated in-app "Delete My Data" control is planned for a future update.)
• Opt out of analytics — turn off Customize → Anonymous Analytics in the App at any time; email team@good-dopamine.app to request deletion of analytics data tied to your installation identifier; or delete the App to stop collection immediately.
• Revoke Screen Time access — Settings → Screen Time on your device.
• Revoke notification permissions — Settings → Notifications on your device.

Depending on your jurisdiction, you may also have rights to access, correct, port, restrict, or object to the processing of your personal information, and to withdraw consent. Because nearly all of your data never reaches us, the fastest way to exercise these rights is usually directly in the App. For anything else, email team@good-dopamine.app and we will respond within the time required by applicable law (generally 30–45 days). We will not discriminate against you for exercising these rights.

California residents. We do not sell or share personal information as those terms are defined by the CCPA/CPRA, and we have not done so in the preceding 12 months. The categories we collect are identifiers (a pseudonymous installation ID) and internet or network activity (anonymous in-app usage events). You may turn off analytics in the App, and request access to or deletion of this information at team@good-dopamine.app.

EEA and UK residents. In the EEA and UK, analytics is off by default and we collect it only with your consent (Article 6(1)(a) GDPR), which you give through the in-app prompt and can withdraw at any time by turning off Customize → Anonymous Analytics. Withdrawing consent does not affect the lawfulness of processing before withdrawal. You may also lodge a complaint with your local supervisory authority. Mixpanel may store data in the United States; those transfers are made under the European Commission's Standard Contractual Clauses.

7. Children's privacy

The App is not directed to children under 16, and we do not knowingly collect personal information from them. If you believe a child under that age has used the App and provided us with personal information, contact team@good-dopamine.app and we will delete it.

Good Dopamine is designed as a self-directed digital wellbeing tool. It is not a parental monitoring product, and it does not report your activity to any other person or account.

8. Security

We use industry-standard safeguards, including encryption in transit (TLS) for analytics events and Apple's on-device data protection for everything stored locally. Keeping essentially all of your data on your device — and operating no server that could be breached — is itself our strongest security measure. That said, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

9. Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date above and, where the change is significant, provide notice in the App before the change takes effect. Continued use of the App after the effective date means you accept the updated policy.
