Flattr was founded by developers and hackers and we know that your apps
and hacks with our API will only help to promote more use of Flattr in
supporting content creators. We hope that common sense and good faith
will make up the basis for a great ecosystem and therefore we try to
keep the list of API rules as short as possible.
However, we reserve the right to change these policies and/or terminate
your API access at any time if we find it necessary for protecting our
users', partners', and own rights.
Current policies for using the Flattr API:
- Always make sure to have our users' consent before acting on their
behalf. Flattr is about money, don’t make your users think your messing
around with their money.
- Comply with any requirements or restrictions imposed on content by
respective owners (our users).
- Make it possible for users to revoke access to their Flattr account
from within your app at any time.
- Make it clear in your app that it is using Flattr but is not an
official Flattr application. Please read our guidelines on how to use
the Flattr name and logos.
- Web integrations should have a link to http://flattr.com.
- Our API has several functions (eg. revenue share, partner rights,
etc.) which require special credentials to use. Please
contact us at if you want to use them.
Name and logo guidelines
To avoid confusion for your users and ours, here are some simple
guidelines for how to use the Flattr name and logos in your application,
website or service. If you have any further questions, please contact us.
- make it clear that your app is using Flattr, using appropriate
explanation within the description or functionality of your
application or site
- use Flattr in a referential phrase such as “powered by”, “connected
to” or similar
- design your site, logos and titles with unique branding elements that
are clearly distinct from Flattr
- ensure that any Flattr logos or titles are displayed less prominently
than those of your application or site.
- imply false affiliation, sponsorship or partnership of your
application or site with Flattr. For example, calling your app
“aFlattr” or Flattapp is fine but calling it “Flattr for Amazon” is not.
- use Flattr logos in a disparaging or misleading manner.
