Terms of Service

Last updated June 6, 2026

1. Agreement to these terms

These Terms of Service ("Terms") govern your access to and use of Fragrance Engine (the "Service"), available at fragrance-engine.com. By creating an account or using the Service you agree to these Terms. If you do not agree, do not use the Service.

2. Who runs the Service

Fragrance Engine is operated by an individual sole operator ("we", "us", or "our"). You can reach us at [email protected] for any question about these Terms or the Service.

3. What the Service is, and what it is not

The Service turns a written description into a suggested fragrance formula, and analyzes formulas and materials you create or import. Every figure the Service produces, including pyramid structure, projection, longevity, sillage, cost, and material roles, is a computed estimate derived from physical data. It is a starting point for a working perfumer, not a guarantee of how a finished blend will behave.

The Service is a creative and analytical tool. It is not a safety authority, a regulatory authority, a testing laboratory, or a source of medical, legal, or professional advice. It does not certify that any formula is safe to wear, safe to sell, or compliant with any standard or regulation. Any compliance or allergen reference shown in the Service is informational only and may be incomplete.

4. Your responsibility for what you make

Fragrance and aroma materials are chemicals. Handling, diluting, wearing, gifting, and selling them carries real risks, including skin sensitization, allergic reaction, and flammability. You are solely responsible for:

• safely sourcing, handling, storing, and disposing of every material you use,
• verifying the safety, skin tolerance, and suitability of anything you make before you or anyone else uses it,
• any testing, certification, labeling, insurance, and regulatory compliance required to make, give away, or sell a product in your jurisdiction.

You use the Service and anything produced with it at your own risk.

5. Accounts

You must be at least 18 years old to create an account. You agree to provide accurate information, to keep your login credentials secure, and to be responsible for all activity under your account. Tell us promptly if you believe your account has been compromised.

6. Subscriptions, billing, and trials

Paid plans (Studio and Studio Pro) are billed through our payment processor, Stripe. By subscribing you authorize recurring charges on the cycle you select (monthly or annual) until you cancel. Free trials, where offered, convert to a paid subscription at the end of the trial unless you cancel before it ends.

• You can cancel at any time from your account or the billing portal. Cancellation stops future renewals and takes effect at the end of the current paid period.
• Except where required by law, payments are non-refundable, and partial periods are not refunded.
• We may change prices or plan features. We will give reasonable notice of a price change before it applies to your next renewal.
• You are responsible for any taxes that apply to your subscription.

7. Acceptable use

You agree not to misuse the Service. You will not attempt to break, overload, scrape at scale, reverse engineer, or gain unauthorized access to the Service or other users' data, and you will not use the Service to break the law or infringe anyone's rights.

8. Your content and the Formulary

You keep ownership of the formulas, accords, notes, and other content you create or import ("Your Content"). The Service is a private workspace by default.

The Formulary is an optional community library. If you choose to publish an edition to the Formulary, you grant us a non-exclusive, worldwide, royalty-free license to host, display, and let other users view and take that published edition into their own workspace, for as long as it stays published. You can request removal of an edition you published.

When you publish, you confirm that you have the right to share what you publish, and that it does not misrepresent another brand's product as your own original work. Naming a commercial fragrance as inspiration is fine; passing off a trademarked product as your own creation is not.

Moderation. We review published Formulary editions and may remove anything that infringes rights, is unsafe, is misrepresented, or otherwise breaks these Terms. We aim to review reports of problem content within 48 hours, though that is a goal, not a contractual guarantee. To report content, email [email protected].

9. Our intellectual property

The Service itself, including its software, design, the curated material catalog, the engine, and the Fragrance Engine name and marks, belongs to us and is protected by intellectual property law. These Terms do not give you any right to our brand or software beyond using the Service as intended.

10. Disclaimers

The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that any estimate, formula, or piece of data it provides is accurate, complete, safe, or fit for your purpose.

11. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, goodwill, or for any personal injury or property damage, arising out of or related to your use of the Service or anything you make with it. To the maximum extent permitted by law, 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 one hundred United States dollars (US$100).

Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, including liability arising from our own gross negligence or willful misconduct.

12. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, and costs (including reasonable legal fees) arising from your use of the Service, your content, or your breach of these Terms, including any claim related to a product you made, gave away, or sold, except to the extent the claim arises from our own gross negligence, willful misconduct, or violation of law.

13. Termination

You can stop using the Service and close your account at any time. We may suspend or end your access if you breach these Terms or use the Service in a way that creates risk or legal exposure. Provisions that by their nature should survive termination will survive, including ownership, disclaimers, limitation of liability, and indemnification.

14. Changes to these terms

We may update these Terms from time to time. If we make a material change, we will update the date above and, where appropriate, give notice in the Service. Continuing to use the Service after a change means you accept the updated Terms.

15. Dispute resolution

Before filing any claim, you agree to first contact us at [email protected] and give us 30 days to try to resolve the issue informally. Most concerns can be settled this way.

Class action waiver. To the maximum extent permitted by law, you and we agree that any dispute will be brought only in an individual capacity, and not as a plaintiff or class member in any class, collective, or representative action.

Either party may still bring an individual claim in small claims court if the claim qualifies.

16. Governing law

These Terms are governed by the laws of the State of New Hampshire, United States, without regard to its conflict-of-law rules. Any dispute that is not resolved informally or in small claims court will be governed by New Hampshire law.
