Terms of use
The rules for using Cardle, in plain terms.
These terms and Privacy & data together cover your use of Cardle. Last updated 14 October 2026.
Contact
Questions about these terms go to admin@cardle.dev.
Who can use Cardle
You must be 18 or older to use Cardle, and you confirm that you are the first time you sign in. Sign-up is open to anyone with a Google account until Cardle has 200 accounts; after that, new accounts join a waitlist and an administrator enables each one. If we learn that an account belongs to someone under 18, we'll remove its access and delete its data.
Your content
What you add to Cardle (cards, notes, links and files) stays yours. You give Cardle a limited, non-exclusive permission to host, copy, process, transform, display and transmit it only as needed to operate features you request, including connected services, AI assistants and personalized recommendations. This permission does not transfer ownership and lasts only while Cardle is entitled to retain the content under the Privacy & data notice.
Agreeing to these terms does not give Cardle permission to use your private content to train or improve a model shared across accounts. That use requires a separate, affirmative opt-in describing the content, purpose, provider, retention and withdrawal effects.
You're responsible for having the right to add what you add.
Acceptable use
Don't use Cardle to:
- store or share anything unlawful, or anything that infringes someone else's rights;
- upload malware, or anything meant to harm the service or other people;
- try to reach another account's data, probe or overload the service, or get around its limits;
- resell or redistribute access to the service.
Keep your sign-in, Connect AI tokens and connected-service tokens to yourself; you're responsible for what's done with them.
Copyright complaints
Everything in Cardle is private to the account that added it. If you still believe something stored in Cardle infringes your copyright, email admin@cardle.dev with:
- the work you believe is infringed;
- where it is in Cardle, in enough detail for us to find it;
- your name, postal address, phone number and email address;
- a statement that you have a good-faith belief the use isn't authorised by the owner, its agent or the law;
- a statement that your notice is accurate and, under penalty of perjury, that you are the owner or authorised to act for them;
- your physical or electronic signature.
We'll remove or disable the material promptly and tell the account holder. If your material was removed and you believe that was a mistake, reply to that email explaining why. We remove the accounts of repeat infringers.
No warranty, and limits on liability
Cardle is free and provided "as is" and "as available". We don't promise it will always be available, error-free, or that data can never be lost, so keep your own copy of anything important.
To the extent the law allows, Cardle's operator isn't liable for indirect or consequential losses, or for lost data, profits or opportunities, and total liability for any claim is limited to what you paid to use Cardle in the 12 months before it. Nothing here limits liability that the law doesn't allow to be limited, or your rights as a consumer.
Ending your use
You can stop using Cardle at any time, and ask for your data to be exported or deleted (see your rights).
We may suspend or remove an account's access if it breaks these terms, or to protect the service or other people. What happens then is described under Privacy & data, "When access is removed".
Changes to these terms
We may update these terms. The date at the top changes when we do, and we'll tell you in the app or by email before a significant change takes effect. If a change would materially expand how existing private content is used — for example, to train a shared model — Cardle will not apply it retroactively without the separate affirmative agreement described above. Continued use may indicate acceptance of other changes only to the extent permitted by law.
Governing law
These terms are governed by the laws of India, and the courts of India have jurisdiction over any dispute about them. This doesn't take away any protection the consumer law of your own country gives you.
