Privacy Policy

1. Data We Collect

We may collect and process the following categories of data:

1. Data you provide directly

   • Wallet addresses you choose to track.
   • Support or feedback messages and any data you include.
   • Information you provide when contacting support by email.

2. Data generated by app usage

   • App settings (for example language, theme, and certain local preferences).
   • Subscription status (free/premium).
   • Device and app telemetry (events, diagnostics, performance, crash data).
   • App usage data (such as first launch date, session frequency, and feature usage).
   • Device settings (such as language preference).
   • Mobile carrier information.
   • Device and technical data (such as device type, unique device ID or advertising ID where available and permitted, IP address, operating system, and app/browser version).

3. Transaction and purchase metadata

   • Subscription transaction status and product identifiers received from Apple.
   • We do not receive your full payment card details; Apple processes billing.

4. Data from third-party/public sources

   • Market and blockchain data requested to provide app functionality.
   • Public blockchain records associated with wallet addresses you track.

5. Advertising-related data (free tier)

   • Ad request/impression/click context and technical identifiers made available by ad SDKs, subject to platform permissions and your settings.

Data may be stored locally on your device or in your personal iCloud account. You can remove local app data by deleting the app. iCloud data management is handled through your Apple account settings.

2. Special Note on Crypto Data

Wallet addresses and on-chain transaction records can be personal data where they relate to an identifiable person. Quasar treats tracked wallet addresses and related blockchain history as personal data when required by law.

Quasar does not request or store private keys or seed phrases.

3. Why We Process Data and Legal Bases (GDPR)

We process personal data under one or more GDPR legal bases:

• Article 6(1)(b) Contract: to provide core Service functions you request (price tracking, wallet view, subscriptions).
• Article 6(1)(c) Legal obligation: to comply with legal duties (for example accounting, tax, lawful disclosure requests).
• Article 6(1)(f) Legitimate interests: to maintain security, prevent abuse/fraud, debug, improve reliability, and operate the Service.
• Article 6(1)(a) Consent: where required for specific tracking/advertising actions under applicable laws (including platform-level consent signals).

If we rely on legitimate interests, we apply a balancing test and protect user rights. Drafting references for EU section: GDPR (EUR-Lex), Article 6 GDPR, Article 13 GDPR, Article 46 GDPR, Article 77 GDPR, European Commission SCC guidance

4. Cookies and Similar Technologies

Because Quasar is an app, we primarily use SDK/device-level identifiers and local storage rather than browser cookies. We may use analytics, diagnostics, and ad technologies provided by service partners. Where consent is legally required, we request/obtain it through available platform mechanisms.

5. Sharing of Personal Data

We may share personal data with:

• Infrastructure and analytics providers (for example Firebase Analytics, Crashlytics, Performance Monitoring).
• Advertising providers (for example Google AdMob) for free-tier monetization.
• Payment/subscription infrastructure (Apple App Store and StoreKit flow).
• Data providers and network endpoints required for market/wallet features.
• Professional advisors, auditors, insurers, and authorities when legally required.
• Successors in a merger, acquisition, or asset transfer.

We do not sell personal data in exchange for money. Where possible, data is processed in aggregated and used to improve app performance and user experience.

6. International Data Transfers

Some recipients may process data outside the EU/EEA/UK/Switzerland. Where required, we use appropriate transfer safeguards, such as:

• Adequacy decisions.
• European Commission adequacy decisions.
• Standard Contractual Clauses (SCCs), supplementary measures.
• Other lawful transfer mechanisms under Chapter V GDPR.

7. Data Retention

We keep personal data only as long as necessary for the purposes in this policy, including legal, accounting, and security needs. Typical retention approach:

• Wallet tracking data: until you remove the wallet from Quasar, plus limited backup/log retention.
• Diagnostics and analytics events: 12 months by default, unless needed longer for security or legal reasons.
• Subscription/accounting records: for legally required retention periods.
• Support correspondence: until resolution plus a reasonable archive period.

When retention is no longer necessary, we delete or anonymize data.

8. Security Measures

We use technical and organizational measures designed to protect personal data, including access controls, least-privilege practices, transport encryption, and monitoring. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.

9. Your GDPR Rights

Subject to legal limits, you may have rights to:

• Access your personal data.
• Rectify inaccurate data.
• Erase data ("right to be forgotten").
• Restrict processing.
• Data portability.
• Object to processing based on legitimate interests.
• Withdraw consent where processing is based on consent (without affecting prior lawful processing).
• Lodge a complaint with your local supervisory authority.

To exercise rights, contact us. We may need to verify your identity before completing requests.

10. Automated Decision-Making

Quasar does not use solely automated decision-making that produces legal or similarly significant effects on you, as described in Article 22 GDPR.

11. Children

Quasar is not intended for children under 12. We do not knowingly collect personal data from children under 12. If you believe a child provided personal data, contact us and we will take appropriate action.

12. Third-Party Services

Quasar relies on third-party providers and public endpoints to deliver market data, wallet information, analytics, and ads. Their processing is governed by their own terms and privacy notices. Examples include:

• Apple App Store / StoreKit
• Google Firebase
• Google AdMob
• Market/public blockchain data endpoints used by app features

The app may contain links to third-party sites or services. We do not control their content or privacy practices and encourage you to review their privacy policies.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If changes are material, we will provide notice in-app and/or by other reasonable means. The "Last updated" date above indicates the latest revision.

14. Legal Basis for Processing (EU/EEA)

If you are in the EU/EEA, Quasar processes personal data under one or more of these legal bases:

• Performance of a contract (to provide app functionality and premium features).
• Legitimate interests (security, fraud prevention, diagnostics, and service improvement).
• Consent (where required, including certain analytics/tracking activities).
• Compliance with legal obligations.

15. Contact Us

If you are in the EU and have unresolved concerns, you may contact your national data protection authority.
