Terms of Service

Effective date: 17 July 2026 · Version 1.3

These Terms of Service (the "Terms") govern your use of the Stellary mobile application, the website stellary.cloud, and related services (together, the "Service"). The Service is operated by Mattias Olandersson and Olle Larsson, private individuals based in Sweden ("we", "us"). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

These Terms also serve as the end-user license agreement for the app. Where you downloaded the app from Apple's App Store, section 13 (Apple-specific terms) also applies.

1. The Service

Stellary is a reading-tracking app: you can build a personal library, log reading sessions (with optional ambient sounds), set goals, maintain streaks, watch your reading come alive as a sky of stars, and read together with friends through friendships and book clubs. Parts of the Service work without an account; account-based features (such as sync, friends, and clubs) require one. How we handle your personal data is described in our Privacy Policy, which forms part of your agreement with us.

2. Eligibility

You must be at least 13 years old to use the Service. By using the Service you confirm that you meet this requirement and that any registration information you provide is accurate.

3. Your account

You are responsible for keeping your login credentials confidential and for all activity under your account. Choose a username that does not infringe anyone else's rights or impersonate another person. Notify us at hello@stellary.cloud if you suspect unauthorized use of your account. You can delete your account at any time from within the app; deletion permanently erases your data as described in the Privacy Policy.

4. License to use the app

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the Stellary app on devices you own or control, for your personal, non-commercial use, in accordance with these Terms and — for the App Store version — Apple's Usage Rules in the App Store Terms of Service. We (and our licensors) retain all rights, title, and interest in the Service, including its software, design, artwork, and branding. You may not copy, modify, distribute, sell, lease, reverse-engineer, or create derivative works of the Service except to the extent mandatory law permits it.

5. Your content

You keep ownership of the content you create in the Service — your library, reading logs, club posts, and other material ("User Content"). You grant us a non-exclusive, worldwide, royalty-free license to host, store, reproduce, and display your User Content solely as needed to operate, back up, and improve the Service — for example, showing your posts to members of a club you posted in, or your reading activity to friends you have connected with. This license ends when you delete the content or your account, except for copies in routine backups (which expire on their own schedule) and content other users have legitimately interacted with in shared spaces (for example, a club discussion may be disassociated from you rather than deleted, to preserve the conversation for others).

You are responsible for your User Content. Do not post content you do not have the right to share.

6. Acceptable use

You agree not to misuse the Service. In particular, you must not:

We may remove content or restrict, suspend, or terminate accounts that violate these rules (see section 10). You can report abusive content or behavior to hello@stellary.cloud; we review reports and act within 24 hours where objectionable content is involved.

7. Third-party content

Book information in the Service (titles, covers, page counts, subjects) is sourced from third-party catalogues, including ISBNdb and Open Library. We do not control and cannot guarantee the accuracy or completeness of this metadata, and it remains subject to its providers' terms. Any third-party links open outside the app at your own discretion.

8. Subscriptions and purchases

The core of Stellary is free. We offer optional premium features ("Stellary Premium", currently sold as the "Stellary Infinite" subscription; the commercial name may change without affecting these Terms) — for example an expanded library, importing your library from Goodreads, additional book clubs, custom shelves, ambient reading sounds, advanced statistics, shareable stat cards, streak protection, and book recommendations — as auto-renewing subscriptions or one-time purchases, bought exclusively through Apple's in-app purchase system. We use RevenueCat to manage purchase entitlements; how it processes data is described in the Privacy Policy. Where premium features are offered, the following applies:

9. Availability and changes to the Service

We aim to keep the Service available and your data safe, but the Service is provided by two private individuals, not a company with a service-level agreement. We may modify, add, or remove features, or suspend or discontinue the Service (in whole or in part) at any time. If we discontinue the Service entirely or remove functionality that a paid subscription materially depends on, we will give reasonable advance notice where practicable, and you can export your data at any time using the in-app export function. For paid features, statutory consumer remedies remain unaffected.

10. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access, or remove content, if you materially or repeatedly violate these Terms, if required by law, or if the Service is discontinued. Where reasonable, we will warn you first and give you the opportunity to remedy the violation and to export your data; in cases of serious abuse (such as attacks on the Service or unlawful content) we may act immediately. Sections that by their nature should survive termination (including 5, 11, 12, and 15) survive.

11. Disclaimer of warranties

The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement, to the maximum extent permitted by applicable law. We do not warrant that the Service will be uninterrupted, error-free, or that data loss will never occur — please use the export feature for anything you cannot afford to lose. This section does not limit any warranty or remedy that consumers are entitled to under mandatory Swedish or EU law.

12. Limitation of liability

To the maximum extent permitted by applicable law: (a) we are not liable for indirect or consequential damages, loss of profits, or loss of data arising from your use of, or inability to use, the Service; and (b) our total aggregate liability for all claims relating to the Service is limited to the greater of (i) the amount you paid us for the Service in the 12 months before the claim arose and (ii) EUR 50.

Nothing in these Terms excludes or limits our liability for gross negligence, willful misconduct, death or personal injury, or any other liability that cannot be excluded or limited under applicable law. If you are a consumer in the EU/EEA, you retain all mandatory statutory rights and remedies, and these Terms are not intended to and do not restrict them.

13. Apple-specific terms

If you downloaded the app from Apple's App Store, the following additional terms apply and prevail over conflicting terms above:

14. Changes to these Terms

We may update these Terms from time to time — for example when we add features, or when legal requirements change. For material changes we will notify you in the app or by email at least 30 days before they take effect, and you may terminate your account before that date if you do not accept them. The current version, with its effective date, is always available at stellary.cloud/terms. Continued use of the Service after changes take effect constitutes acceptance.

15. Governing law and disputes

These Terms are governed by the laws of Sweden. If you are a consumer residing in the EU/EEA, you also enjoy the protection of the mandatory consumer-protection rules of your country of residence, and nothing in this section deprives you of the right to bring proceedings in your local courts.

If you have a complaint, please contact us first at hello@stellary.cloud — we will try to resolve it informally. Consumers in Sweden may also refer disputes to the Swedish National Board for Consumer Disputes (Allmänna reklamationsnämnden, ARN), Box 174, 101 23 Stockholm, www.arn.se. Otherwise, disputes are subject to the jurisdiction of the Swedish courts, with Malmö District Court as first instance where the parties may agree on venue.
