Sift Terms & Conditions

The rules and guidelines for using Sift

Last updated: 5 July 2026

These Terms of Service ("Terms") are a legal agreement between you and Khueon Studios ("Sift", "we", "us") governing your use of the Sift mobile application and related services (the "App"). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your country) and able to form a binding contract to use the App. If you use the App on behalf of an organization, you represent that you are authorized to accept these Terms for it.

2. The service

Sift lets you import documents you own (PDF and EPUB) and read them as AI-generated condensed summaries, and it gathers "ideas" from your reading. The App offers a free tier (which includes the original imported text) and a paid subscription ("Pro") that unlocks AI condensation, idea gathering, and related features. We may add, change, or remove features at any time.

3. License

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own personal, non-commercial use, in accordance with the usage rules of the app store you obtained it from.

4. Your content and responsibilities

  • You are responsible for what you import. You may only import documents that you own, that are in the public domain, or that you otherwise have the legal right to use and to process into summaries. You must not import content that infringes any copyright, trademark, or other right, or that is unlawful.
  • You retain your rights. We do not claim ownership of the documents you import. You grant us only the limited rights needed to process your content to provide the features you request (for example, transmitting document text to our AI provider to generate a summary, as described in our Privacy Policy).
  • Representations. By importing content, you represent that you have the necessary rights and that your use of the App with that content does not violate any law or third-party right. You are solely responsible for your content and for how you use any summaries you generate.

5. AI-generated content — important disclaimer

  • Condensed summaries and gathered ideas are produced by automated AI systems. They may be inaccurate, incomplete, outdated, or misleading, and may omit or misrepresent parts of the original work.
  • Summaries are provided for convenience only and are not a substitute for reading the original work, which remains the authoritative source. Do not rely on AI output for medical, legal, financial, safety, or other important decisions.
  • You are responsible for independently verifying any information before relying on it. We make no warranty regarding the accuracy or fitness of AI-generated content.

6. Acceptable use

You agree not to:

  • use the App for any unlawful purpose or to process content you have no right to use;
  • reverse engineer, decompile, or attempt to extract the source code of the App, except where permitted by law;
  • interfere with, overload, or abuse our backend or AI processing service, or attempt to bypass usage limits, security, or the paywall;
  • use automated means to access the service in a manner that places an unreasonable load on it;
  • resell, sublicense, or commercially exploit the App or its output without our permission.

7. Subscriptions, billing, and cancellation

  • Purchase. Pro is offered as an auto-renewing subscription (and/or other plans shown in the App). Payment is charged to your Apple App Store or Google Play account at confirmation of purchase.
  • Auto-renewal. Subscriptions renew automatically for the same period at the then-current price unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
  • Managing and cancelling. You can manage or cancel your subscription in your Apple App Store or Google Play account settings after purchase. Deleting the App does not cancel your subscription.
  • Free trials / offers. If a free trial or introductory offer is provided, any unused portion is forfeited when you purchase a subscription, where applicable.
  • Refunds. Purchases are handled by the app stores and are subject to their refund policies. We generally cannot grant refunds directly; please contact Apple or Google.
  • Price changes. We may change subscription prices. Changes apply to future billing periods and, where required, will be notified to you and/or require your consent in accordance with store rules.

8. Intellectual property

The App, including its software, design, and branding, is owned by us and our licensors and is protected by intellectual property laws. Except for the license granted above, no rights are transferred to you. If you send us feedback or suggestions, you grant us a perpetual, royalty-free license to use them without obligation to you.

9. Third-party services

The App relies on third-party services, including Apple, Google (Firebase), OpenAI, and RevenueCat. Your use of the App may also be subject to their terms, and we are not responsible for third-party services. See our Privacy Policy for how data is shared with them.

10. Disclaimer of warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT AI OUTPUT WILL BE ACCURATE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN DISCLAIMERS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE APP. OUR TOTAL LIABILITY FOR ANY CLAIM WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE APP IN THE 12 MONTHS BEFORE THE CLAIM, OR (B) USD $50.

12. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, or expenses (including reasonable legal fees) arising from your content, your use of the App, or your violation of these Terms or any law or third-party right.

13. Termination

You may stop using the App at any time. We may suspend or terminate your access if you violate these Terms or misuse the service. Sections that by their nature should survive termination (including ownership, disclaimers, limitation of liability, and indemnification) will survive.

14. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date and, where appropriate, provide notice in the App. Your continued use after changes take effect constitutes acceptance.

15. Governing law

These Terms are governed by the laws of the Islamic Republic of Pakistan, where the Developer is based, without regard to its conflict-of-laws rules, and the courts of Gilgit-Baltistan, Pakistan have non-exclusive jurisdiction.

If you are a consumer resident in the European Economic Area (EEA) or the United Kingdom, this choice of law and forum does not deprive you of the protection of the mandatory consumer-protection provisions of the law of your country of residence, and you keep the right to bring proceedings in the courts of your country of residence. We process your personal data in accordance with the EU/UK General Data Protection Regulation (GDPR), as described in our Privacy Policy.

16. Apple App Store — additional terms

These terms apply if you obtained the App from the Apple App Store:

  • This agreement is between you and us only, not with Apple. Apple is not responsible for the App or its content.
  • The license granted is a non-transferable license to use the App on any Apple-branded products you own or control, as permitted by the App Store Usage Rules.
  • We, not Apple, are solely responsible for maintenance and support of the App. Apple has no obligation to furnish any support.
  • In the event the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation, and any other claims, losses, liabilities, damages, costs, or expenses are our responsibility.
  • We, not Apple, are responsible for addressing any claims by you or a third party relating to the App, including product-liability, legal or regulatory, and intellectual-property claims.
  • You represent that you are not located in a country subject to a U.S. Government embargo or designated a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
  • For support, contact [email protected].
