Terms

Last updated November 9, 2026. Covers the Sidepaper iPhone app, which is in beta, and this website. Sidepaper is made by Catalyst Logic AI (“we”).

Agreeing to these terms

These terms are an agreement between you and Catalyst Logic AI. By using Sidepaper you agree to these terms and to our privacy policy. If you don't agree, please don't use it.

It's a beta

• Sidepaper is in testing. Features may change, stop working or be removed, and the app may have bugs.
• Unless you turn on sync, your boards live only on your phone, and we don't have a copy. If the app, your phone or a backup fails, we can't recover them. Even with sync on, keep your own copies of anything important.
• Sidepaper is free during the beta. If we ever add paid plans, we'll tell you the price before charging anything, and you'll choose whether to pay.

Your content is yours

You own what you write, draw, photograph and record in Sidepaper. We don't claim any rights to it.

When you send text to ChatGPT or Claude through Sidepaper, you give us permission to store that text and pass it on, only so we can deliver it to the assistant you chose and bring the reply back to you. We don't use it for anything else.

Assistants and suggestions

• ChatGPT is run by OpenAI and Claude is run by Anthropic, under their own terms. Sidepaper is independent and not affiliated with either.
• Organizing results and assistant replies are suggestions. They can be wrong. Nothing is applied to your board until you approve it, and one tap undoes what you applied. You're responsible for checking anything before you rely on it.

Your account

You need an account to use Sidepaper. Keep your sign-in secure and give accurate details. You can delete your account any time in the app. We may suspend or close an account that breaks these terms.

Acceptable use

Please don't use Sidepaper to:

• break the law, or infringe anyone else's rights;
• send content that you don't have the right to share;
• try to get into accounts, servers or data that aren't yours;
• overload, disrupt or attack our servers, or get around limits we set;
• copy, resell or reverse-engineer our servers or services.

Our software

We let you use the Sidepaper app for your own personal or work use while these terms apply. The app, its name and its design belong to Sidepaper. Parts of Sidepaper use open-source software under its own licenses, which are listed in the app.

No warranty

Sidepaper is provided as it is and as available, without warranties of any kind, to the extent the law allows. We don't promise that it will be uninterrupted, error-free or fit for a particular purpose.

Limits on liability

To the extent the law allows, Sidepaper isn't liable for indirect or consequential losses, or for lost data, profits or business, arising from your use of the app or the website. Some places don't allow these limits, so they may not apply to you.

Changes and ending

We may update these terms. When we do, we'll change the date at the top, and we'll tell you in the app if a change matters. You can stop using Sidepaper at any time. We may end the beta or stop offering Sidepaper. If we do, we'll give notice where we can, and your boards will stay on your phone.
