Privacy Policy

Effective date: October 11, 2026

RankPulse ("we", "us") provides a macOS application that archives and displays Amazon US Best Sellers data. This policy explains what we collect when you use the App, why, and your choices.

We do not collect your browsing history, Amazon account, payment card details, location, contacts, or cookies from your browser. Payments are processed entirely by Apple.

1. Data we collect

1.1 Account information (Sign in with Apple)

Your Apple user identifier;
Your email address, or a private email-relay address if you choose to hide your email;
Your display name, if you choose to provide it.

1.2 Subscription information

To provide paid features we store your subscription status, Apple transaction identifiers, purchase/renewal dates, and introductory-trial status. We never receive your payment method — that is held by Apple. See also Apple's Privacy Policy.

1.3 Content you create

Watch groups, tracked ASINs and notes you enter are stored so they can sync across your Macs.

1.4 Technical data

A device identifier you generate within the App, authentication tokens, and minimal server logs (request time, status) used for security and debugging.

1.5 Product data

The App displays publicly available Amazon Best Sellers information (rank, title, price, rating, reviews, images, deals). This is market data, not personal data about you.

2. How we use data

To create and secure your account and authenticate sign-ins;
To determine your trial or subscription entitlement;
To sync and display the groups and notes you create;
To provide, maintain and troubleshoot the App;
To comply with legal obligations.

3. Legal bases (GDPR/UK)

We process your data under contract (to provide the service), our legitimate interests (security, debugging, abuse prevention), consent (where you provide it), and legal obligation. You may withdraw consent at any time.

4. Who we share data with

Apple Inc. — sign-in and in-app purchase processing;
Cloud infrastructure providers (currently Volcengine/ByteDance) — hosting the database and API under contractual confidentiality;
Authorities where required by law.

We do not sell, rent or trade your personal data, and we never use it for advertising.

5. International transfers

Data may be processed in regions other than your own (for example, servers in Hong Kong and mainland China). We use appropriate contractual and technical safeguards for such transfers.

6. Retention

We keep account data while your account is active. When you delete your account, your personal data (groups, notes, devices, tokens, subscription links) is permanently removed. Server logs are retained for a limited period. Product market data may remain because it is not personal data.

7. Your rights

Subject to applicable law (GDPR, CCPA, China PIPL), you may request access, correction, deletion, restriction or portability of your personal data, object to processing, and withdraw consent. You can delete your account at any time in the App under Account & Subscription → Delete Account. To exercise other rights, contact us at support@getrankpulse.com. We will respond within the period required by law.

8. Security

Access is encrypted in transit (HTTPS/TLS), data is isolated per user, and database access is restricted to the service. No method is perfectly secure, but we work to protect your data.

9. Children

The App is not directed to children under 16 (or the age required in your jurisdiction), and we do not knowingly collect their data.

10. Changes

We may update this policy. Material changes will be shown in the App or on this page with a revised effective date.
