The fine print, kept kind

Terms of Use

Last updated: 28 October 2026

The app

SisterStars helps you set intentions, notice and keep meaningful moments, follow small rituals and guided challenges, and write affirmations. It is meant for personal reflection and enjoyment.

Not professional advice

Nothing in SisterStars, including AI-written texts, is medical, psychological, financial or legal advice, and it does not promise any particular outcome. If you are struggling, please reach out to a professional or, in an emergency, your local emergency number. The app shows crisis resources when they may be needed.

Who can use it

You must be at least 16 years old to use SisterStars.

Subscriptions

• Using SisterStars requires a subscription (yearly or monthly). Prices are shown in the app before you buy, in your local currency.
• The yearly plan may include a free trial. If you do not cancel at least 24 hours before the trial ends, the subscription starts and you are charged.
• Subscriptions renew automatically at the end of each period unless cancelled at least 24 hours before it ends.
• Payment is handled by Apple (App Store) or Google (Google Play). Manage or cancel your subscription in your App Store or Google Play account settings. Deleting the app does not cancel it.
• Refunds are handled by Apple or Google under their policies.

Your content

What you write in SisterStars is yours. We only use it to run the features you choose (for example backup or AI writing), as described in our Privacy Policy. You are responsible for what you write and should not use the app to store anything unlawful.

AI-written text

AI writing is optional. Texts are generated automatically, can be imperfect, and are offered as a starting point for you to edit. Use your own judgement before relying on them.

Fair use

Please don't misuse the service: no attempts to break, overload or reverse engineer it, and no automated access. To keep AI writing available for everyone, it has a monthly limit shown in the app.

Availability and changes

We work to keep SisterStars running well, but we cannot guarantee it will always be available or free of errors. We may update the app and these terms; if a change matters, we will tell you in the app before it applies.

Ending

You can stop using SisterStars and delete your account at any time in Settings → Account. We may suspend accounts that seriously break these terms.

App Store terms

If you downloaded SisterStars from the App Store, Apple's Standard End User License Agreement also applies. Apple is not responsible for the app or its support.

Liability and law

Nothing in these terms limits rights you have under the consumer law of your country. To the extent the law allows, our liability is limited to the amount you paid for SisterStars in the twelve months before the claim.
