Terms of Service

Last updated: August 29, 2026

These terms are an agreement between you and Larso Labs, LLC, a Wyoming limited liability company ("Larso Labs", "we", "us"), and govern your use of the Sifria app and the sifria.app website (together, the "Service"). By using the Service you agree to these terms. If you do not agree, do not use the Service.

1. The Service

Sifria is a personal reading companion: a library manager, reading log, and discovery tool. We are continuously improving the Service, and features may be added, changed, or removed over time. Where a feature is labeled beta or early access, it may be less stable than the rest of the app.

2. Eligibility and accounts

You must be at least 13 years old to use the Service. You are responsible for your account and for keeping access to it secure. Provide accurate information, and keep your sign-in method (email, Google, or Apple) accessible — if you use the app without linking a sign-in method and lose your device, we may not be able to recover your data.

3. Your content

The content you create in Sifria — reviews, notes, quotes, photos, collections — is yours. You grant us a limited, worldwide, non-exclusive license to host, store, back up, display, and process that content solely to operate and improve the Service, and to share it in the ways you choose (for example, share cards or a public shelf you enable). This license ends when you delete your content or your account, except for copies in routine backups that expire on their own schedule.

You are responsible for what you post. Keep saved quotes within reasonable bounds of quotation, and do not upload content you have no right to use, or content that is unlawful, infringing, or abusive.

4. Book catalog data

Book metadata, covers, and catalog search results come from licensed third-party databases and are provided "as is". We do not guarantee that catalog information — titles, editions, page counts, covers, or availability — is complete or accurate. Book covers and related materials remain the property of their respective rights holders.

5. Acceptable use

You agree not to:

6. Deal finder and purchases

The Service may include a deal finder that surfaces offers for books from third-party retailers. We are not the seller of those books: purchases happen with the retailer, under the retailer's terms, prices, and policies. If you buy through a link in Sifria, we may earn a commission from the referral at no additional cost to you. We are not responsible for retailers' pricing, availability, delivery, or service.

7. Fees

Sifria is currently free to use. We may introduce optional paid features or subscriptions in the future; if we do, pricing and terms will be presented clearly before you are charged, and purchases made through the app stores are also subject to the stores' terms.

8. Our intellectual property

The Service — including the app, website, design, and the Sifria name and marks — belongs to Larso Labs and its licensors. These terms do not grant you any right to use our branding, and no rights are granted except as expressly stated here.

9. Third-party services

The Service relies on third-party providers (such as cloud hosting, sign-in providers, and the app stores) and may link to third-party sites. We are not responsible for third-party services, and your use of them is governed by their own terms.

10. Termination

You can stop using the Service and delete your account at any time. We may suspend or terminate access that violates these terms, harms the Service, or creates legal risk — where practical, we will notify you and give you a chance to export your data. Sections that by their nature should survive termination (including 3, 8, and 11–14) survive.

11. Disclaimers

The Service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that data will never be lost — keep in mind that the app also stores your library locally on your device.

12. Limitation of liability

To the maximum extent permitted by law, Larso Labs will not be liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, or goodwill, arising from your use of the Service. To the same extent, we are not liable for: the conduct or content of other users; service interruptions, outages, or server failures; loss or corruption of data; or the acts, omissions, or security incidents of third-party services, including information disclosed through them. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us for the Service in the twelve months before the claim or fifteen U.S. dollars (US $15). Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

13. Indemnification

You agree to indemnify and hold Larso Labs harmless from claims arising out of your content, your use of the Service in violation of these terms, or your violation of any law or third-party right.

14. Governing law and disputes

These terms are governed by the laws of the State of Wyoming, United States, without regard to conflict-of-law rules.

Informal resolution first

Before starting any formal proceeding, contact us at the address below with a description of the dispute — most concerns can be resolved quickly by email. Both sides agree to try in good faith to resolve any dispute informally for at least 30 days before proceeding further.

Binding individual arbitration

Any dispute arising out of these terms or the Service that is not resolved informally will be resolved by binding arbitration on an individual basis, administered by the American Arbitration Association under its Consumer Arbitration Rules or, if the AAA is unavailable or declines to administer, by JAMS under its consumer arbitration rules and minimum standards. If neither is available, the parties will agree on another administrator or, failing agreement, a court will appoint an arbitrator under 9 U.S.C. § 5; the unavailability of any administrator does not invalidate this agreement to arbitrate. The Federal Arbitration Act governs the interpretation and enforcement of this section. The arbitrator's award may be entered as a judgment in any court with jurisdiction. Either party may instead bring an individual claim in small claims court, and either party may seek injunctive relief in court for infringement or misuse of intellectual property.

Class-action waiver

You and Larso Labs each waive the right to a jury trial and the right to participate in a class, collective, consolidated, or representative action. Claims may be brought only in an individual capacity. If this class-action waiver is found unenforceable as to a particular dispute, the entire arbitration provision does not apply to that dispute, which will instead be brought exclusively in the state or federal courts located in Wyoming, and you consent to their jurisdiction.

If you do not agree

If you do not agree to resolve disputes this way, do not use the Service — you can end this agreement at any time by deleting your account and uninstalling the app, as described in Section 10.

15. App store terms

If you downloaded Sifria from the Apple App Store or Google Play, the store's terms also apply. Apple and Google are not parties to these terms, are not responsible for the Service or its content, and have no obligation to provide support or maintenance for it.

16. Changes to these terms

We may update these terms as the Service evolves. Material changes will be announced in the app or by email before they take effect; continuing to use the Service after they do means you accept the updated terms.
