Privacy Policy

• Account information: your name, email address, username and avatar, and sign-in details if you use Google, Apple or Facebook sign-in.
• Habit and progress data: the habits you create, check-ins, schedules, reminders, goals, tracking style and app preferences.
• Journal entries (Spark Pro): the notes and moods you choose to write after completing a habit.
• Subscription status: whether you have Spark Pro. Payments are handled by Apple or Google, and we never receive your card details.
• Device and usage information: device type, operating system, app version, language, notification tokens, advertising identifiers, and diagnostic and usage events.
• Photos you add to a habit are stored only on your device and are not uploaded to our servers.

• Provide your account, sync your habits across devices and run core features.
• Generate AI coaching, habit suggestions, tips, Spark Sunday Reviews and translations.
• Send the reminders and notifications you have turned on.
• Show ads in the free version and measure how they perform.
• Keep the service secure, prevent abuse, fix problems and improve features.
• Provide customer support and send service, legal and policy updates.

To provide AI coaching, Spark Sunday Reviews, habit tips and translations, we send relevant information to our AI provider, OpenAI, through our servers. Depending on the feature, this can include your first name or username, habit names and progress, goals, reminder preferences, tracking style and language, and, for Spark Pro weekly reviews, the journal entries and moods you wrote that week. Under OpenAI's API terms, this content is not used to train its models. AI-generated content can be inaccurate and is not medical, nutritional or psychological advice. Journal entries are optional, so please avoid including sensitive details you do not want processed in this way.

The free version of HabitSpark AI shows ads. Ads are provided by Google AdMob and its partners Meta Audience Network, Unity Ads and InMobi, which may collect device information, your IP address and your device's advertising identifier to show, limit and measure ads. In the UK and EEA, we ask for your consent before showing personalised ads. You can reset or limit ad tracking in your device settings at any time. Spark Pro removes ads.

For users in the UK, personal data is processed under lawful bases recognised by the UK GDPR, including contract performance, legitimate interests, consent where required, and compliance with legal obligations. Personalised advertising is based on your consent.

We do not sell personal data. If you use friend features, people you connect with can see your username, avatar and progress statistics. We may also disclose information where required by law or to protect rights, property and safety. We share information with the following service providers under appropriate safeguards:

• Google Firebase: sign-in, database hosting, cloud functions, notifications, analytics and remote configuration.
• RevenueCat: managing Spark Pro subscriptions.
• Apple and Google: app store payments and sign-in.
• Meta (Facebook): optional Facebook sign-in and friend features.
• OpenAI: AI-powered features, as described above.
• Advertising partners: as described in the Advertising section.

Your information may be processed outside the UK. Where required, we implement appropriate safeguards such as UK-approved contractual protections or other lawful transfer mechanisms.

We retain personal data only for as long as reasonably necessary to provide the service, comply with legal obligations, resolve disputes, enforce agreements, and support legitimate business operations. You can delete your account at any time in Settings, or contact us to request deletion of your personal data.

We maintain technical and organisational safeguards designed to protect personal data. No transmission or storage method is completely secure, so absolute security cannot be guaranteed.

Depending on your location, you may have rights to access, correct, erase, restrict, or object to certain processing, and to request portability of personal data. UK users may also complain to the ICO at ico.org.uk.

HabitSpark AI is not directed to children under 13, or any higher minimum age required by local law. If we become aware of unlawful data collection from a child, we will take appropriate remedial action.

We may update this Privacy Policy from time to time. Material changes will be reflected by an updated effective date and, where required by law, additional notice.
