1. Scope
This Privacy Policy applies to FormulaMind and the legal pages hosted at novarynix.com, including /formulamind/privacy/. It is written for users, parents, guardians, educators, and App Store reviewers who need a clear description of how the app handles information.
This English version is the authoritative Privacy Policy for FormulaMind worldwide.

| Data type | Linked to identity? | Used for tracking? | Purpose |
|---|---|---|---|
| Purchase History | Linked | No | App Functionality |
| Crash Data | No | No | App Functionality |
| Performance Data | No | No | App Functionality |

Data that stays on your device or in your private iCloud
Learning data such as formula progress, completed lessons, favorites, wrong-answer records, quiz history, saved preferences, and app settings is stored locally on the user's device unless Members enable private iCloud sync.
When private iCloud sync is enabled, learning data is stored in the user's private iCloud container, iCloud.com.novarynix.formulamind. This local and private iCloud learning data is not collected by the developer and is not transmitted to FormulaMind servers.
3. Information FormulaMind May Process
FormulaMind does not require users to publish a profile or provide a physical address to use the core educational experience. Depending on the app version and features enabled, FormulaMind may process the following categories of information:
- Local learning data: formula progress, completed lessons, favorites, wrong-answer records, quiz history, saved preferences, and app settings stored on the device.
- iCloud sync data for Members: if sync is enabled, learning data such as progress, favorites, and wrong-answer records may be stored in the user's private iCloud container through Apple CloudKit.
- Diagnostics: crash reports, performance data, error logs, device and app metadata, and reliability signals used to identify and fix technical problems.
- Configuration and analytics data: Firebase installation ID / IDFV, feature flag and remote configuration signals, screen views, onboarding events, quiz events, and paywall events, subject to the consent controls described below.
- Purchase and entitlement data: purchase receipt or entitlement signals received from Apple to unlock membership features.
- Support contact data: information a user chooses to provide when contacting support.
4. How Information Is Used
Information is used to operate FormulaMind, remember user preferences, provide membership features, sync learning data when enabled, diagnose crashes, monitor reliability, prevent abuse, respond to support requests, and improve the educational experience.
FormulaMind does not sell personal information. FormulaMind does not share personal information for cross-context behavioral advertising. FormulaMind does not use personal information to track users across other apps or websites.
5. Analytics, Diagnostics, and Third-Party Services
The current release embeds the Sentry SDK for crash diagnostics, performance data, and other diagnostic data. Sentry is used to understand technical problems and improve reliability.
Sentry is not used for advertising, is not used to track users across apps or websites, and does not collect personal information, screenshots, formula content, quiz answers, or free-text user input from FormulaMind.
The release binary also embeds Firebase Remote Config (Google), which is used for feature flags and remote configuration. Firebase Remote Config processes a Firebase installation ID and collects no PII and no learning content.
The release binary also embeds Firebase Analytics (Google), which collects a Device ID, such as the Firebase installation ID / IDFV, and product-interaction events, such as screen views, onboarding, quiz, and paywall events. This data is not linked to a stable identity, is not used for tracking or advertising, and IDFA / ATT are not used.
Analytics is consent-gated: it is disabled by default in GDPR/UK-style regions until the user grants consent in-app, enabled for aggregate analytics only elsewhere, and globally controllable in the app.
Third-party services may process information under their own terms and privacy policies. Relevant providers may include Apple for App Store purchases, iCloud, and CloudKit; Sentry for diagnostics; and Google/Firebase for Remote Config and Analytics.
6. Subscriptions and Purchases
FormulaMind Membership is an auto-renewing subscription.
All purchases are processed by Apple via the App Store. FormulaMind does not see, store, or transmit payment card details.
The app receives a purchase receipt / entitlement signal only, as needed to confirm access to membership features.
Purchase History may be linked to the user's Apple ID. Its sole purpose is App Functionality. It is not used for tracking or for advertising.
7. iCloud Sync (Members)
When sync is enabled, learning data such as progress, favorites, and wrong-answer records is stored in the user's own private iCloud container via Apple CloudKit. The container identifier is iCloud.com.novarynix.formulamind.
FormulaMind does not operate any server that stores user learning data.
Sync availability and quotas are governed by the user's Apple ID and Apple's iCloud service.
Users can disable sync or delete the iCloud data via iOS Settings.
8. Legal Bases for Processing (EEA/UK users)
Where GDPR or UK GDPR applies, FormulaMind relies on the following legal bases under Article 6:
- Performance of a contract: delivering the app and subscription.
- Legitimate interests: diagnosing crashes, improving reliability, and preventing abuse.
- Consent: where required for optional features. In GDPR/UK regions, Firebase Analytics is collected only after the user grants consent in-app, and consent may be withdrawn at any time. Marketing data is not collected.
9. Your Privacy Rights
EEA / UK (GDPR / UK GDPR)
You may have rights to access, rectify, erase, restrict, or port your personal data; object to certain processing; withdraw consent; and lodge a complaint with a supervisory authority.
California (CCPA/CPRA)
California residents may have rights to know, delete, and correct personal information; opt out of "sale" or "sharing" of personal information, which FormulaMind does not do; limit use of sensitive personal information, which FormulaMind does not collect; and receive non-discriminatory treatment for exercising privacy rights.
Other jurisdictions
Similar rights may apply under local law depending on where you live.
How to exercise
Email [email protected] with the subject "Privacy Request". FormulaMind will respond within 30 days or as otherwise required by law.
10. Children's Privacy
FormulaMind is rated 4+ but is not designated "Made for Kids".
FormulaMind does not knowingly collect personal information from children under 13, or the equivalent minimum age in the user's jurisdiction, such as 16 in some EEA countries.
Parents or guardians may contact [email protected] to request deletion.
11. Retention
- Local on-device data: retained until the user deletes it, resets the app, or uninstalls the app.
- iCloud-synced data: lives in the user's iCloud account and is governed by Apple's retention; the user can delete it via iOS Settings.
- Diagnostics (Sentry): retained per the diagnostic provider's default retention window, approximately 90 days, and then deleted or anonymized.
- Purchase records: handled by Apple under Apple's App Store and Apple ID policies.
12. Security
FormulaMind uses reasonable technical and organizational measures appropriate for an educational app, including HTTPS for public legal pages and reliance on established platform providers. No method of transmission or storage is perfectly secure, so absolute security cannot be guaranteed.
13. International Data Transfers
Purchase signals are processed by Apple in the United States and other regions. Diagnostic data is processed by Sentry in United States / EU regions. Analytics and configuration data processed by Google/Firebase may be processed in the United States and other regions.
For transfers out of the EEA / UK, FormulaMind relies on appropriate safeguards offered by these providers, including Standard Contractual Clauses and adequacy decisions where applicable.
14. Changes to This Policy
This policy may be updated as FormulaMind changes. Material updates will be reflected by changing the date above and publishing the revised policy at /formulamind/privacy/.
