Information we may ask for

We try to collect as little information as possible. Most of what we ask for is the minimum we need to provide the services we do, and most of the information that is supplied is discarded as soon as it has served its purpose. Depending on the services you use on, we may ask for the following information:

  • URLs of web pages or feeds (stored temporarily on our servers to improve performance)
  • Your Kindle email address and, optionally, an email address on your approved Amazon Kindle list (used for sending articles, but not stored on our servers after sending completes)
  • Your API key if you register as a paying customer
  • Your email address if you register as a paying customer or join our forums

Occasionally we also enable logging on our servers for statistical analysis. When logging is enabled, IP addresses are stored. We destroy logs once they have served their purpose.

Push to Kindle: credits and Patreon login

The amount of credits remaining are stored in your browser. We do not store them on the server and they do not get sent to the server.

Although you can login via Patreon when using Push to Kindle, we do not link your Patreon account to the Push to Kindle email addresses you enter. Your browser records whether you are logged in or not, not our server. We do not send any Patreon information to our servers when you send or download articles.

We use Patreon’s OAuth service if you login with Patreon. We request the minimum information we can using their API – your public profile. It does not contain your email address. We only use the data returned by Patreon to tell us which tier you’re on, which determines the number of credits you get assigned when using the app.

What we do with the information we gather

The information we collect is used to ensure optimal system performance and to improve the services we offer. We do not share this information except when necessary to carry out the requested task – for example, to deliver web articles to your Kindle using your Kindle email address, we have to communicate and share information with Amazon’s servers.

If logging is enabled, the information collected (such as IP addresses) is never shared with anyone else.


We are committed to ensuring that your information is secure. In order to prevent unauthorised access or disclosure, we have put in place suitable software and procedures to safeguard and secure the information we collect online.


None of our services currently rely on cookies or local storage, but we do use them to improve the experience of some of our services (for example, to remember the Kindle address we should send articles to next time you use the Push to Kindle service).

Cookies and local storage in no way gives us access to your computer or any information about you, other than the data you choose to share with us.

Most web browsers allow cookies and local storage, but you can usually modify your browser setting to not use them if you prefer. You can still take advantage of our website with them disabled.
