Sift Labs LLC · Last updated: July 31, 2026
Welcome to Sift. These Terms of Use ("Terms") are an agreement between you and Sift Labs LLC ("Sift," "we," "us") governing your use of the Sift mobile application, sifthealth.app, and related services (together, the "Service"). By creating an account or using the Service, you agree to these Terms. If you don't agree, don't use the Service.
Section 16 contains provisions that apply only in your country, including which law governs these Terms and how disputes are resolved. Those provisions take precedence over anything to the contrary elsewhere in these Terms.
NOTICE TO USERS IN THE UNITED STATES: SECTION 16.1 CONTAINS A BINDING ARBITRATION AGREEMENT AND A CLASS-ACTION WAIVER. IF YOU LIVE IN THE UNITED STATES, YOU AGREE TO RESOLVE DISPUTES WITH SIFT THROUGH INDIVIDUAL ARBITRATION RATHER THAN IN COURT, AND YOU GIVE UP THE RIGHT TO A JURY TRIAL AND THE RIGHT TO PARTICIPATE IN A CLASS ACTION. YOU MAY OPT OUT OF THIS AGREEMENT WITHIN 30 DAYS. SECTION 16.1 EXPLAINS HOW.
Sift gives you evidence-based information about ingredients in food and personal care products. It's information, not medical advice. Sift+ is an auto-renewing subscription you manage through your app store. We work hard to be accurate, but product formulas change and databases have gaps. Always read the physical label, especially for allergies.
Sift analyzes ingredients in food and personal care products and presents scores, flags, explanations, sourcing information, and suggested alternatives based on published research and regulatory data.
Sift is an informational tool. It is not medical advice, diagnosis, or treatment, and it is not a substitute for guidance from a physician, dermatologist, allergist, dietitian, or other qualified professional. Never disregard professional advice or delay seeking it because of something you read in Sift.
Sift is not an allergy-safety tool. Product formulations change without notice, labeling varies by market, and no database is complete. If you have a food allergy, ingredient sensitivity, or medical condition, always read the physical product label and consult the manufacturer. Do not rely solely on Sift for decisions where an error could harm your health.
A note on disordered eating. Sift is designed to help you understand what’s in products, not to guide how much you eat or to restrict what you eat. If you have or have had a disordered relationship with food, some of what Sift shows you may not be helpful, and we’d encourage you to talk to a professional about whether it’s right for you.
Sift is not a guarantee of better health. Health is shaped by many factors (overall diet, quantity and frequency of use, exercise, environment, and individual circumstances), none of which Sift measures. Sift tells you what is in a product. It does not tell you what that product will do for you.
Sift has no contractual or financial relationship with the producers or distributors of the products it evaluates. Specifically:
Sift is funded by Sift+ subscriptions.
Sift Scores are produced by applying a consistent, documented evaluation methodology to published research and regulatory data. The same methodology is applied to every product. No product or brand receives individual treatment.
A Sift Score, a flag, a watch item, a sensitivity notice, an “Our Take” summary, or any similar editorial content is an opinion about a product’s ingredient composition, based on our reading of the available evidence. It is not a statement of fact about the product, the brand, or the manufacturer.
Score bands and labels describe the score, not the product. Where Sift describes a product or an ingredient using terms such as “worth caution,” “worth avoiding,” or similar language, and where a product falls into a lower or higher scoring band, those terms refer only to the result of our evaluation method. They are not statements that a product is unsafe, unfit for use, unfit for consumption, illegal, non-compliant, adulterated, or of poor quality, and they should not be read that way.
Where Sift notes a potential concern about an ingredient, we may apply a precautionary approach and flag it where a risk is credibly suspected but not established. We do not claim scientific authority. We summarize and interpret published work, and reasonable experts may disagree with our interpretation.
Science and regulation change. Despite our efforts to keep pace, we cannot guarantee that every evaluation reflects the most recent study or the most recent regulatory change in every market.
Suggested alternatives and curated selections such as Standouts are chosen by the same neutral method. No brand pays to appear in them, and inclusion does not mean a product is the best available.
You need an account to use most of the Service. You agree to provide accurate information, keep your credentials secure, and accept responsibility for activity under your account. You must be at least 13 years old (or the minimum age of digital consent in your country, if higher) to use the Service.
You also agree that:
We may suspend or terminate accounts that violate these Terms, and we may delete accounts that have been inactive for at least twelve months. If you believe your credentials have been compromised, tell us immediately.
Some features require a paid subscription (“Sift+”).
You agree not to:
Accounts that breach this section may be suspended or deleted without notice, and we may pursue legal remedies where the circumstances warrant it.
Sift may let you submit product information and photographs, for example when you scan a product we don’t yet have.
When you submit a contribution, you confirm that:
You grant us a worldwide, royalty-free, perpetual, irrevocable, sublicensable license to use, reproduce, modify, and display your contributions in connection with the Service, including commercially. You retain ownership of what you submit.
You are responsible for the contributions you make. Submitting content you don’t have the right to submit, or deliberately submitting false information, may result in removal of the contribution, suspension or deletion of your account, and legal action where the circumstances warrant it.
Feedback and suggestions you send us may be used to improve the Service without obligation to you.
The Service, including Sift Scores, our evaluation methodology, ingredient descriptions, editorial content, sourcing breakdowns, databases, designs, the Sift name and logo, and the software, is owned by Sift Labs LLC or its licensors and protected by intellectual-property laws.
We grant you a personal, non-exclusive, non-transferable, revocable license to use the app for your own non-commercial purposes, for as long as you use the Service. This license does not transfer any ownership, and does not give you any right to access, use, or disclose our source code, methods, or algorithms.
Content belonging to third parties, including brand names, logos, images, photographs, packaging designs, and text, remains the exclusive property of its owner and is protected by copyright, trademark, and other laws. It appears in Sift for the purpose of identifying and describing products.
You agree to respect the rights of those third parties, not to infringe their rights directly or indirectly, and not to exploit that content in any way. Product names and brand trademarks shown in the app belong to their respective owners, and their appearance does not imply affiliation with or endorsement by them.
By creating an account, you agree that we may send you service communications relating to your account: password resets, receipts, security notices, and changes to these Terms or our Privacy Policy. These are part of the Service and cannot be opted out of while your account is active.
We may also send occasional updates about new features, ingredient research, and Sift’s work. Every one of those includes a one-click unsubscribe link, and unsubscribing has no effect on your account or your Sift+ subscription. If you have enabled push notifications, we may send alerts relating to your activity in the app, such as letting you know when a score you requested is ready. You can turn push notifications off at any time in your device settings.
The Service relies on third-party providers, including app store billing infrastructure, subscription management, hosting, and email delivery. Their services are governed by their own terms, and we are not responsible for services we don’t control.
Sift may link to external resources such as scientific studies and regulatory publications. We don’t control those resources, we aren’t responsible for their content or availability, and linking to them is not an endorsement.
We aim to keep Sift available, but we can’t guarantee uninterrupted access. The Service may be unavailable because of maintenance, updates, network or power failures, hosting provider issues, device incompatibility, or events outside our control. Interruption does not give rise to compensation or refund beyond what the law requires.
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF ACCURACY, COMPLETENESS, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT PRODUCT DATA, SCORES, INGREDIENT INFORMATION, OR SOURCING RATINGS ARE CURRENT, COMPLETE, OR ERROR-FREE.
Product data in Sift reflects information from product labels, manufacturers, and public sources. We operate checks, but we do not chemically analyze products ourselves, and errors in composition data or ingredient detection can occur. It is your responsibility to check the packaging of any product where accuracy matters to you.
Some jurisdictions don’t allow certain warranty exclusions, so parts of this section may not apply to you. Nothing here affects statutory rights you have as a consumer.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, SIFT LABS LLC WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM YOUR USE OF OR INABILITY TO USE THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE OR (B) US $100.
Nothing in these Terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, for fraud, and for your statutory consumer rights. Some jurisdictions do not allow these limitations, in which case our liability is limited to the least amount permitted by applicable law.
To the extent permitted by applicable law, you agree to indemnify and hold harmless Sift Labs LLC and its officers, members, employees, and contractors from claims, losses, liabilities, damages, costs, and reasonable legal fees arising out of your breach of these Terms, your misuse of the Service, or content you contribute.
If you downloaded the app from Apple’s App Store: these Terms are between you and Sift Labs LLC, not Apple. Apple has no obligation to provide maintenance or support for the app and is not responsible for addressing claims relating to the app, including product-liability, legal-compliance, or IP claims. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You represent that you are not located in a country subject to a U.S. government embargo and are not on any U.S. government restricted-party list.
If you downloaded the app from Google Play, Google is similarly not a party to these Terms and is not responsible for the app.
The provisions below apply according to the country you use Sift in, and take precedence over anything to the contrary elsewhere in these Terms.
These Terms are governed by the laws of the State of Nevada, without regard to conflict-of-law rules.
Informal resolution first. Before starting any formal proceeding, you agree to send us a written notice describing the dispute and a proposed resolution, to team@sifthealth.app, and to negotiate in good faith for sixty (60) days.
Venue. For any matter not subject to arbitration under this section (and for entering judgment on an arbitration award), you consent to the exclusive jurisdiction of the state and federal courts located in King County, Washington, and agree not to raise the defense of forum non conveniens.
Binding arbitration. If informal resolution does not settle the dispute, you and Sift agree that it will be resolved exclusively by binding individual arbitration rather than in court. You are giving up the right to litigate disputes in court before a judge or jury. The arbitrator’s decision is final, subject to a limited right of appeal under the Federal Arbitration Act, and any court with jurisdiction may enforce the award.
Class-action waiver. Any proceeding to resolve a dispute will be conducted solely on an individual basis. Neither you nor Sift will seek to have a dispute heard as a class action or in any other representative capacity, and no arbitration will be combined with another without the written consent of all affected parties.
Procedure. Arbitration will be administered by the American Arbitration Association under its Consumer Arbitration Rules, and will be commenced in King County, Washington. You may request a telephonic or in-person hearing under the AAA rules; in a dispute involving US $10,000 or less, any hearing will be telephonic unless the arbitrator finds good cause otherwise. The arbitrator may award the same individual relief a court could, and may award declaratory or injunctive relief only to you individually and only to the extent needed to satisfy your individual claim.
One-year limitation. To the extent permitted by law, any claim or dispute must be filed within one year of when it first could have been filed, whether in arbitration or in small claims court. Claims not filed within one year are permanently barred.
Small claims. Either party may bring an individual claim in small claims court instead of arbitration, if the claim qualifies.
HOW TO OPT OUT. IF YOU DO NOT WISH TO BE BOUND BY THIS ARBITRATION AGREEMENT AND CLASS-ACTION WAIVER, YOU MUST TELL US IN WRITING WITHIN 30 DAYS OF FIRST ACCEPTING THESE TERMS. EMAIL team@sifthealth.app WITH THE SUBJECT LINE “ARBITRATION OPT-OUT,” OR WRITE TO US AT THE ADDRESS IN SECTION 20 MARKED “ATTN: ARBITRATION OPT-OUT.” YOUR NOTICE MUST INCLUDE YOUR NAME, THE EMAIL ADDRESS ON YOUR ACCOUNT, AND A CLEAR STATEMENT THAT YOU DO NOT WISH TO RESOLVE DISPUTES THROUGH ARBITRATION. OPTING OUT WILL NOT AFFECT YOUR ACCOUNT OR YOUR USE OF SIFT IN ANY WAY.
Severability and survival. If the class-action waiver is found unenforceable as to a particular claim, that claim will be severed and heard in court, while the remainder of this section continues to apply. If applicable law does not permit binding arbitration or a class-action waiver to apply to you, these provisions apply to the fullest extent the law permits. This section survives termination of these Terms.
These Terms are governed by the laws of England and Wales, and the courts of England and Wales have jurisdiction, except that if you live in Scotland or Northern Ireland, you may also bring proceedings in your local courts.
Nothing in these Terms affects your statutory rights under the Consumer Rights Act 2015. You have the right to cancel a subscription purchased directly from us within 14 days, though by starting to use Sift+ immediately you agree that the service begins during that period and you may be charged for what you have used. Subscriptions bought through the App Store or Google Play are subject to their refund policies.
These Terms are governed by the laws of Ireland, and the courts of Ireland have jurisdiction. Nothing in these Terms affects your statutory rights under Irish and EU consumer law, including the Consumer Rights Act 2022.
You have the right to withdraw from a subscription purchased directly from us within 14 days without giving a reason. If you ask us to begin the service during that period, you may be charged in proportion to what you have used before withdrawing. Subscriptions bought through the App Store or Google Play are subject to their refund policies.
You may also use the European Commission’s Online Dispute Resolution platform to submit a complaint, at ec.europa.eu/consumers/odr.
These Terms are governed by the laws of the Province of British Columbia and the federal laws of Canada applicable there.
Before starting any formal proceeding, the parties agree to meet and negotiate in good faith for sixty (60) days from written notice of the dispute. Notice may be sent to team@sifthealth.app. Nothing in these Terms limits rights you have under applicable provincial consumer protection legislation. Residents of Quebec retain all rights under the Consumer Protection Act (Quebec), and where those rights conflict with these Terms, they prevail.
These Terms are governed by the laws of New South Wales, Australia.
Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. For major failures with the service, you are entitled to cancel your service contract with us and to a refund for the unused portion, or to compensation for its reduced value. You are also entitled to be compensated for any other reasonably foreseeable loss or damage. Nothing in these Terms excludes, restricts, or modifies those guarantees. Where liability can be limited, our liability is limited to resupplying the service or paying the cost of resupply.
These Terms are governed by the laws of New Zealand.
Nothing in these Terms limits your rights under the Consumer Guarantees Act 1993 or the Fair Trading Act 1986 where you acquire the Service as a consumer. Where you acquire the Service for business purposes, the Consumer Guarantees Act does not apply.
We may modify or discontinue features at any time. We may update these Terms; changes take effect fourteen (14) days after we post them, and for material changes we’ll notify you in the app or by email before they take effect. Continued use after that date constitutes acceptance. If you don’t agree, stop using the Service and cancel any subscription.
You can stop using the Service and delete your account at any time in Settings → Account. We may suspend or terminate your access for violations of these Terms. Sections that by their nature should survive, including 3, 7, 8, 12, 13, 14, and 16 (including the arbitration agreement), survive termination.
Severability. If any provision of these Terms is found invalid or unenforceable, the remaining provisions remain in full force.
No waiver. Our failure to enforce any right or provision is not a waiver of it.
Entire agreement. These Terms, together with our Privacy Policy, are the entire agreement between you and Sift regarding the Service.
