Terms of Service

Last updated September 24, 2026

These terms are an agreement between you and Lost Ink LLC (“Lost Ink,” “we,” “us”) for your use of Lost Ink: our website, web app, iPhone app, and tablet integrations (the “Service”). By using the Service, you agree to these terms. If you don’t agree, please don’t use it.

Your account

You must be at least 13 years old to use Lost Ink, and if you’re under 18 you need your parent’s or guardian’s permission. Keep your sign-in secure and let us know right away if you think someone else is using your account. You’re responsible for activity on your account.

Your content stays yours

You own your notebooks, handwriting, and everything else you bring to Lost Ink (“Your Content”). To run the Service, you give us permission to store, copy, process, and display Your Content, and to share it with the service providers described in our Privacy Policy, only as needed to provide Lost Ink to you. This permission ends when Your Content is deleted from the Service, apart from copies in backups for a limited time.

Please only bring content you have the right to use.

Connected services

Lost Ink works with services such as Google Drive, Google Calendar, reMarkable, SuperNote, Notion, and Apple Reminders and Calendar. When you connect one, you allow us to access it on your behalf as described in our Privacy Policy. Those services are run by other companies under their own terms, and we aren’t responsible for them.

Automatic results can be wrong

Lost Ink reads handwriting and finds to-dos, dates, and search results automatically. These results can be incomplete or mistaken. Please check anything important, and don’t rely on Lost Ink as your only record of deadlines, appointments, or other critical information.

The beta

Lost Ink is in beta. Features may change, break, or be removed, and the Service may sometimes be unavailable. The beta is free. If we introduce paid plans, we’ll tell you in advance, and you won’t be charged unless you choose a paid plan.

Using Lost Ink responsibly

Please don’t:

• use the Service to break the law or infringe anyone’s rights;
• try to access other people’s accounts or data;
• probe, disrupt, or overload the Service, or get around its security or usage limits;
• copy, resell, or reverse engineer the Service, except where the law allows it; or
• use automated means to access the Service other than the features we provide.

If you find a security problem, please report it to security@lostink.ai rather than exploiting it.

Feedback

We welcome your ideas. If you send us feedback, we may use it to improve Lost Ink without any obligation to you.

Ending your use

You can stop using Lost Ink at any time and ask us to delete your account by emailing privacy@lostink.ai. We may suspend or close accounts that break these terms, or that put the Service or other users at risk. If we end the beta or shut down the Service, we’ll give you reasonable notice where we can, so you have time to save what you need.

Disclaimers

The Service is provided “as is” and “as available.” To the fullest extent the law allows, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We don’t promise the Service will be uninterrupted, error-free, or that Your Content will never be lost, so keep your original notebooks on your tablet.

Limitation of liability

To the fullest extent the law allows, Lost Ink won’t be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, or goodwill. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim or US $50. Some places don’t allow these limits, so they may not apply to you.

Indemnity

If you use the Service in a way that breaks these terms or the law, you agree to cover reasonable costs, including legal fees, that result from claims against Lost Ink because of it.

Governing law

These terms are governed by the laws of the State of California, without regard to its conflict-of-law rules. Any dispute will be resolved in the state or federal courts located in California, and you and Lost Ink agree to their jurisdiction.

Changes to these terms

We may update these terms. We’ll post the new version here and update the date above, and if a change is significant we’ll let you know by email or in the app before it takes effect. If you keep using Lost Ink after that, you accept the updated terms.

General

These terms and our Privacy Policy are the whole agreement between you and Lost Ink about the Service. If any part is found unenforceable, the rest stays in effect. If we don’t enforce a term right away, we haven’t waived it. You may not transfer these terms without our consent. We may transfer them as part of a merger, acquisition, or sale of assets.
