Ciela/Terms of use

Terms of use.

Ciela is given away freely. These terms describe the small set of agreements we ask of you in exchange — mostly things you'd expect for a tool that touches your email.

EFFECTIVE · MAY 2026 VERSION · 1.0 PLAIN LANGUAGE

01 · The short versionWhat you're agreeing to.

By downloading and using Ciela, you agree to use it responsibly with email accounts that belong to you (or that you have explicit permission to manage), and you accept that — like all software — Ciela is provided as-is, with no guarantees. We don't collect anything in exchange. There's no account, no payment, no fine print past the obvious.

Use it on email that's yours to clean. Don't blame us if it surprises you. That's most of it.

02 · Acceptable useWhat we ask of you.

You agree that:

  • You will only connect Ciela to email accounts you own or are explicitly authorized to manage. Don't use Ciela to read or clean someone else's inbox without their permission.
  • You will not use Ciela to violate any laws, Google's Gmail API terms, Microsoft's Graph API terms, or anyone else's rights.
  • You will not try to circumvent API rate limits, abuse OAuth, or pretend to be a different application.
  • You will not modify, repackage, and redistribute Ciela in a way that misrepresents who built it or hides that the original is free.

Because Ciela has no accounts and no servers, we cannot suspend or ban a user — there's no user to suspend. If you behave badly, the consequences are between you, Google, and whoever you harmed.

03 · No warrantyAs-is.

Ciela is provided "as is," without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and noninfringement. We do not warrant that the software will be uninterrupted, error-free, or that any classification or cleanup action will be correct.

Plainly: Ciela can mis-classify a sender. The Gmail or Graph API can return an unexpected error. Your network can go down mid-action. We've designed Ciela to fail safely — it moves mail to Trash rather than deleting, and your email provider keeps Trash for thirty days — but you remain in charge of your inbox. Review what Ciela proposes before you confirm it.

04 · Limitation of liabilityWhat we're not on the hook for.

To the maximum extent permitted by applicable law, in no event will Ciela, its authors, or its contributors be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, use, or goodwill, arising out of or in connection with your use of (or inability to use) Ciela — even if advised of the possibility of such damages.

Our total cumulative liability for any claim arising out of these terms or your use of Ciela is limited to the amount you paid for the software, which, since Ciela is free, is zero.

05 · LicenseYou may use it. You may read it.

The Ciela application binaries are provided to you under a free, non-exclusive, non-transferable license to install and run the software on devices you control, for any lawful purpose.

06 · Trademarks"Ciela" is ours.

"Ciela" and "The Inbox Curator" are trademarks of the project. You may refer to Ciela by name in reviews, articles, and discussion — please do — but do not use the marks to imply endorsement, partnership, or affiliation we have not agreed to.

07 · Third-party servicesGoogle and Microsoft.

Ciela interacts with Google's OAuth and Gmail services (Gmail users) and Microsoft's OAuth and Graph API services (Outlook users). Your use of those services is governed by their respective terms and privacy policies. We are not affiliated with, endorsed by, or sponsored by Google or Microsoft.

If either provider changes its API, rate limits, or scope policies in a way that affects Ciela's ability to function, we will adapt as quickly as we reasonably can, but we cannot guarantee continued operation across such changes.

08 · Changes to these termsIf anything material changes.

We may update these terms over time. The version stamp at the top of this page will be bumped, and material changes will be noted in the changelog. Continued use of Ciela after a change indicates your acceptance of the new terms.

09 · Governing lawWhich courts hear what.

These terms are governed by the laws of the jurisdiction in which the Ciela project is published, without regard to its conflict-of-laws provisions. Any dispute arising out of these terms or your use of Ciela will be resolved exclusively in the competent courts of that jurisdiction. If any provision of these terms is held unenforceable, the remaining provisions remain in full force.

Plain-language note: this isn't legal advice and it isn't bullet-proof boilerplate. If your use of Ciela has legal stakes (for example, you're cleaning email tied to an employer, a regulated industry, or a legal matter), please talk to an attorney before doing so.
