Privacy Policy
Last updated: 19 March 2026
This Privacy Policy explains how we collect, use, share, and protect information when you use the Rationalize Life applications and the rationalize.me cloud service on Android, iOS, and other supported platforms (the "Service").
This Policy is designed to meet the transparency requirements of the EU General Data Protection Regulation (GDPR) and to work for users worldwide.
By using the Service, you agree to this Policy. Where we rely on consent (for example, for certain optional analytics where required), you can withdraw it at any time.
1. Data Controller and Scope
The data controller for your personal data is:
This Policy applies to all platforms (Android, iOS, web/desktop) where Rationalize Life is offered and covers data collected via Google Play, the App Store, and our own services.
2. Categories of Data We Process
2.1. Data you provide
- Account data: email address and password or authentication tokens when you register a rationalize.me account or sign in.
- Planning content: goals, projects, tasks, notes, tags, schedules, and related information you enter into the app.
- Support and communication data: messages, troubleshooting details, and contact information when you reach out to us.
2.2. Data collected automatically
Via app runtime and SDKs (including Google Firebase on Android and iOS), we may collect:
- Device and app information (device model, operating system version, app version, language, region, time zone).
- Usage data (screens visited, feature usage, session length, interaction events).
- Diagnostics (crash reports, performance metrics, error logs).
2.3. Data from platforms and third parties
- App stores may provide us with limited, aggregated data such as installs, crashes, and sales according to their own privacy policies.
- For paid features, Google Play and Apple’s App Store share limited purchase and subscription information with us, such as product identifiers, country or region, and whether a purchase or subscription is active, so we can unlock Pro features and cloud sync on your account.
We do not intentionally collect special categories of data (such as health, biometric, or political data) as defined by GDPR; please avoid entering such information where possible.
3. Purposes and Legal Bases (GDPR/EEA)
We process personal data for the following purposes and on these legal bases:
- Provide the Service: create and manage your account, store and sync your planning data, and keep the app functioning across devices (legal basis: performance of a contract, Article 6(1)(b) GDPR).
- Improve and maintain the Service: analyze usage patterns, monitor crashes, and optimize performance (legal basis: our legitimate interests in improving and securing the Service, Article 6(1)(f) GDPR; where required, your consent under Article 6(1)(a)).
- Security and abuse prevention: detect and prevent misuse, security incidents, and fraud (legal basis: legitimate interests and compliance with legal obligations).
- Communication: respond to support requests, send important service announcements, and notify you of changes to Terms or this Policy (legal basis: performance of a contract and legal obligations).
- Manage purchases and subscriptions: verify your entitlement to Pro/offline features and cloud sync based on store receipts and subscription status (legal basis: performance of a contract and our legitimate interest in preventing fraud).
- Legal compliance: comply with legal requirements and respond to lawful requests from authorities (legal basis: Article 6(1)(c) GDPR).
4. Firebase Analytics and Crash Reporting
We use Google Firebase services (Analytics, Crashlytics, and related SDKs) on both Android and Apple platforms to understand app usage and improve stability.
Firebase may collect:
- App instance identifiers and device identifiers (such as IDFV on iOS, Android device identifiers), app version, and operating system information.
- Events about how you use the app (screen views, feature usage, first open, session starts).
- Crash and error information, including stack traces, to help fix problems.
We do not send prohibited sensitive categories of data (such as payment card data or certain children’s data) to Firebase.
On iOS, we provide accurate App Store privacy labels and respect Apple’s data‑use and privacy‑manifest requirements. On Android, we follow Google Play’s user‑data policies and Data Safety requirements.
You can influence analytics behavior through device settings (for example, limiting ad tracking) and, where offered, through in‑app privacy or analytics settings.
5. Cookies, SDKs, and Similar Technologies
The apps do not use traditional browser cookies but rely on SDKs and similar technologies that serve similar purposes, including:
- Storing technical identifiers to differentiate app instances and sessions.
- Remembering preferences and basic configuration.
- Measuring feature usage and performance metrics.
- Supporting crash reporting and debugging.
On iOS and Android, you can manage tracking and analytics permissions through system privacy settings and, when implemented, via in‑app opt‑out controls.
6. Cloud Sync and Storage via rationalize.me
If you enable cloud synchronization:
- Your account data and User Content are stored on servers managed by or for us so that you can access your planner from multiple devices.
- Data is generally encrypted in transit (for example via HTTPS) and stored using reasonable security measures.
- If you choose not to use sync, your data remains on your device only.
You can disable sync at any time. This may limit cross‑device access but does not automatically delete existing cloud data unless you also request account deletion.
7. Data Sharing and Recipients
We share personal data only when necessary:
- Service providers: hosting, database, analytics, crash reporting, customer support, and email services under data‑processing agreements and security obligations.
- App stores and payment processors: Google and Apple process your payment details directly and share limited purchase metadata with us; they act as independent controllers or processors under their own terms and policies.
- Legal and protection: where required by law or to protect our rights, users, or the public.
- Business transfers: in case of merger, acquisition, or restructuring, your information may be transferred with appropriate safeguards.
We do not sell your personal data.
8. International Data Transfers
Your data may be stored and processed in countries outside your own, including outside the EU/EEA. Where GDPR applies and data is transferred to a country without an adequacy decision, we rely on appropriate safeguards, such as Standard Contractual Clauses or equivalent mechanisms, with our service providers.
9. Data Retention
We keep personal data only as long as necessary for the purposes described above:
- Account and sync data: for as long as your account is active.
- Analytics and diagnostics data: for a limited retention period defined in our analytics tools and logs.
- Backup copies: stored for limited periods for disaster recovery, after which they are deleted or anonymized.
If you request deletion of your account or data, we will delete or anonymize personal data within a reasonable time, subject to legal obligations to retain certain data.
10. Your Rights (Especially for EU/EEA/UK Users)
Under GDPR and similar laws, you may have the following rights regarding your personal data:
- Right of access: obtain confirmation and a copy of your personal data.
- Right to rectification: correct inaccurate or incomplete data.
- Right to erasure: have your data deleted in certain circumstances.
- Right to restriction: limit processing in specific situations.
- Right to data portability: receive certain data in a structured, machine‑readable format.
- Right to object: object to processing based on legitimate interests or direct marketing.
- Right to withdraw consent: withdraw consent at any time where processing is based on consent.
To exercise these rights, contact us using the details in Section 13. We may need to verify your identity before acting on your request. You also have the right to lodge a complaint with your local data protection authority, especially in the EU/EEA or UK.
11. Children’s Data
The Service is not directed to children under 16 or the age of digital consent in their country, whichever is higher. We do not knowingly collect personal data from such children; if we discover this has happened, we will delete it as soon as reasonably possible.
If you believe we have collected data from a child, please contact us.
12. Security Measures
We implement appropriate technical and organizational measures to protect your data, including encryption in transit, restricted access, and secure infrastructure. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
13. Platform‑Specific Notes (Android & iOS)
- Android (Google Play): We comply with Google Play’s user‑data policies and Data Safety form requirements and disclose our use of Firebase analytics and crash reporting.
- iOS (Apple App Store): We provide accurate App Store privacy labels and comply with Apple’s data‑use and privacy‑manifest requirements, including for Firebase libraries used on Apple platforms.
In case of any conflict between this Policy and requirements imposed directly by Google or Apple, we will follow the stricter requirement and update this Policy accordingly.
14. Changes to This Privacy Policy
We may update this Policy from time to time. If we make material changes, we will update the "Last updated" date and, where legally required, notify you in the app or via other appropriate channels and, if needed, obtain your consent.
