Privacy Policy

This Privacy Policy describes how Kindlesuite (“we”, “us”) collects, uses, and shares information when you use Kindlesuite (the “Service”), available at kindlesuite.app.

We aim to collect only what is necessary to operate the Service and deliver content to your Kindle device. If you have any question, write to hello@kindlesuite.app.

When you create an account or use the Service, we may collect:

• Account information — your name, email address, and Google profile data returned by Google Sign-In.
• Kindle delivery email — the @kindle.com address you configure so we can email generated documents to your device.
• Reading preferences — the source types you tell us you intend to use during onboarding.
• Conversion history — for each conversion, we store the source URL or file name, mode (article, video, thread, document, text), and the timestamp. We do not retain the full generated PDF after delivery.
• Payment metadata — for purchases, we receive a transaction ID, the email used at checkout, and the amount from our payment processor. We do not store card numbers or banking details — those are handled directly by the processor.
• Technical data — IP-derived country (used to route you to the appropriate payment processor), browser type, and anonymized usage events.

We use the information above to:

• Provide, operate, and improve the Service.
• Deliver converted documents to your Kindle device by email.
• Send transactional emails (welcome, low-credit, purchase confirmation).
• Process payments and prevent fraud.
• Detect, debug, and resolve technical issues.
• Comply with legal obligations.

We do not sell your personal information, and we do not use your content or conversion data to train any machine-learning model.

Kindlesuite processes URLs, social posts, PDFs, and text that you paste or upload. Source content is fetched or read transiently to generate a Kindle-optimized PDF, which is then emailed to your configured Kindle address. We retain a short metadata record of each conversion (URL or file name, timestamp, mode) for your history; we do not retain the generated PDF after delivery.

You are responsible for ensuring you have the right to fetch, extract, or upload the content you submit. See the Terms of Service for the acceptable-use rules.

To run the Service we rely on the following sub-processors. Each is a third party with its own privacy policy. The list reflects services actually in use today; we update it when we add or remove processors.

We use a small number of cookies:

• Session cookie (session_kindleflow) — keeps you signed in. Strictly necessary.
• Analytics — Vercel Analytics collects anonymized page-view data. It does not use cookies for fingerprinting and does not track you across sites.

We retain account information for as long as your account is active. Conversion-history metadata is retained while the account is active so you can see what you have sent to your Kindle. Payment-transaction records are retained as long as required for tax and accounting purposes. Generated PDFs are not stored after they have been emailed to your Kindle device. On account deletion we remove your personal information within 30 days, except where retention is required by law.

Depending on your jurisdiction you may have the right to access, correct, export, or delete your personal information, and to object to certain processing. To exercise any of these rights, email hello@kindlesuite.app from the email address associated with your account.

The Service is not directed to anyone under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.

Our infrastructure providers may process information in regions outside your country of residence, including the United States and the European Union. By using the Service you understand that your information may be transferred to and processed in those regions.

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the “Last updated” date above. Continued use of the Service after a change constitutes acceptance of the updated policy.

Privacy questions, data requests, and complaints can be sent to hello@kindlesuite.app.
