Terms of Use
Last updated: July 5, 2026
Welcome to Custos (“Custos,” “we,” “us,” or “our”), a fragrance-collection and wear-tracking application operated by Custos-Keeper LLC, a Georgia limited liability company. These Terms of Use (“Terms”) govern your access to and use of the Custos application and website at custos-fragrance.com, together with any related websites, pages, mobile applications, and services where these Terms are posted or linked (collectively, the “Service”).
By creating an account or accessing or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree to these Terms, do not access or use the Service.
The Service is a general-audience application that is not directed to children under 13, and we do not knowingly permit children under 13 to create accounts. By accessing or using the Service, you represent and warrant that you are at least 13 years old and are able to form a binding contract with us. If you are under the age of majority where you live, you may use the Service only with the consent and supervision of a parent or legal guardian who agrees to these Terms on your behalf. If you are using the Service on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.
Custos is a personal tool for organizing a fragrance collection and tracking wear. Depending on the features you choose to use, the Service may allow you to:
The Service is currently provided free of charge, and we do not currently charge for the app or any features. The information in the Service, including fragrance notes, accords, and any ingredient or performance data, is provided for general informational purposes only. Fragrance is subjective, and perception varies between individuals. We may add, change, suspend, or discontinue any part of the Service at any time, as described in Section 16.
Free Service; No Backup or Support Obligation. The Service is provided free of charge. We are not obligated to maintain, support, update, or continue the Service, or to preserve any particular feature or data, except as stated in our Privacy Policy or required by law. You are responsible for keeping your own copies of information important to you, and to the maximum extent permitted by law we are not liable for loss, deletion, or corruption of content or data.
To use most features, you must create an account. You agree to:
You may not impersonate any person or entity, create an account for anyone other than yourself without authorization, or access or attempt to access an account that is not yours. We may suspend or terminate accounts as described in Section 15.
“Your Content” means the information you add to the Service, including your collection data, wear-log entries, notes, and optional profile details. As between you and us, you retain all ownership rights in Your Content.
You grant Custos-Keeper LLC a limited, irrevocable, worldwide, non-exclusive, royalty-free license to host, store, back up, reproduce, and display Your Content solely to operate, provide, secure, and maintain the Service for you. This license exists only to run the Service and ends when Your Content is deleted from our active systems, except for residual copies retained for a limited period as described in our Privacy Policy.
You represent and warrant that you have the necessary rights to submit Your Content and that Your Content does not violate any law or the rights of any third party. We do not use Your Content to train artificial-intelligence models.
The Service includes a shared fragrance catalog that all users draw from. If you submit a fragrance that is not already in the catalog, that fragrance record becomes part of the shared catalog so that other users can use it (a “Submission”).
For each Submission, you grant Custos-Keeper LLC and other users of the Service a perpetual, irrevocable, worldwide, non-exclusive, royalty-free license to use, store, reproduce, modify, adapt, publish, and display the Submission as part of the shared catalog and the Service. Because catalog entries are shared, a Submission may remain available to other users even after you delete your account, but it will be de-identified and no longer associated with your account.
The catalog is intended to contain information about fragrances, not personal information about people. You agree not to include personal information in Submissions, and to submit only accurate, lawful information that does not infringe the rights of others. We may review, edit, reject, or remove any Submission at our discretion, and we are not obligated to publish or retain any Submission. We may curate, combine, normalize, de-duplicate, reformat, edit, remove attribution from, or create derivative catalog records from Submissions to maintain and improve the shared catalog.
You agree not to:
We may investigate suspected violations and may restrict, suspend, or terminate access, remove content, or take other appropriate action.
“Ask Claude” is an optional feature that you may enable by providing your own Anthropic (Claude) API key. If you use it:
The Service relies on third-party providers to operate, including (for example) Supabase, Netlify, Anthropic, Open-Meteo, Resend, and content-delivery networks. Your use of the Service may also be subject to those providers’ terms, and we are not responsible for third-party services or their acts or omissions. The Service may contain links to third-party websites or resources provided for convenience only; we do not control and are not responsible for them, and you access them at your own risk.
The Service, including its software, design, user interface, text, graphics, the “Custos” name and logo, and the selection, arrangement, and organization of the shared catalog, is owned by or licensed to Custos-Keeper LLC and is protected by intellectual-property and other laws. We grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Service for your own personal, non-commercial purposes, subject to these Terms. Except as expressly permitted, you may not copy, reproduce, distribute, modify, create derivative works from, publicly display, reverse-engineer, or commercially exploit any part of the Service without our prior written permission. All rights not expressly granted are reserved by Custos-Keeper LLC and its licensors.
If you believe content on the Service infringes your copyright, send a notice to legal@custos-fragrance.com including: your contact information; identification of the copyrighted work; identification and location of the allegedly infringing material; a statement of good-faith belief that the use is unauthorized; a statement under penalty of perjury that the information is accurate and you are authorized to act; and your signature. We may remove content and terminate repeat infringers.
If you submit ideas, suggestions, or feedback, you grant Custos-Keeper LLC a perpetual, irrevocable, worldwide, royalty-free right to use them without restriction or compensation.
Custos is not affiliated with, endorsed by, or officially connected to any perfume house, fragrance brand, or retailer, or to any fragrance database such as Fragrantica, Parfumo, or Basenotes. Fragrance names, brands, and trademarks are the property of their respective owners and are referenced only for identification and informational purposes.
Fragrance information in the Service — including notes, accords, any ingredient or allergen data, and any longevity or projection assessments — is provided for general informational purposes, may be incomplete or inaccurate, and is inherently subjective. The Service does not provide medical, health, safety, or allergen advice. Do not rely on the Service for decisions about allergies, sensitivities, or ingredient safety; always consult the product’s actual labeling and a qualified professional regarding any allergy or medical concern.
THE SERVICE AND ALL CONTENT ARE PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS, without warranties of any kind, whether express, implied, or statutory—all of which are hereby disclaimed, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the Service will be uninterrupted, timely, secure, or error-free, that defects will be corrected, or that the Service or its content will produce any particular result. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.
To the maximum extent permitted by law, Custos-Keeper LLC and its members, owners, and contributors will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, profits, revenue, or goodwill, arising out of or relating to your use of (or inability to use) the Service, even if advised of the possibility of such damages. To the maximum extent permitted by law, our total aggregate liability for any claim relating to the Service will not exceed the greater of the amount you paid us to use the Service (which, for a free service, is US$0) or US$100. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
You agree to indemnify and hold harmless Custos-Keeper LLC and its members, owners, and contributors from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or related to your use of the Service, Your Content, your Submissions, or your violation of these Terms, applicable law, or the rights of any third party.
You may stop using the Service at any time and may delete your account at any time via Settings → Delete my account. We may suspend or terminate your access to the Service at any time, with or without notice, including if we reasonably believe you have violated these Terms or to protect the Service or other users. Upon termination, your license to use the Service ends. Sections that by their nature should survive termination — including Sections 4–5 (licenses granted to us), 9–14, and 16–20 — will survive. Shared-catalog Submissions may remain available to other users on a de-identified basis as described in Section 5 and in our Privacy Policy.
Because the Service is provided free of charge, we may modify, suspend, or discontinue any part of it at any time without liability. We may also update these Terms from time to time. If we make changes, we will update the “Last updated” date above, and for material changes we will provide additional notice where appropriate, such as through in-app notification or email. Your continued use of the Service after changes take effect means you accept the updated Terms.
These Terms are governed by the laws of the State of Georgia, U.S.A., without regard to its conflict-of-laws principles. You agree that the exclusive venue for any dispute not subject to any agreed alternative process will be the appropriate state courts located in Fulton County, Georgia, or the U.S.D.C. for the Northern District of Georgia, Atlanta Division, depending on which of said courts have subject matter jurisdiction. You irrevocably consent to personal jurisdiction there. Before filing any claim, you agree to first contact us and attempt in good faith to resolve the dispute informally. You waive the right to participate in any class action, collective, or representative lawsuit. You will not have the right to join or consolidate claims with claims of any other person.
The Service is operated from the United States and is currently intended primarily for users in the United States. We do not currently market or direct the Service to any other country or region, and we make no representation that the Service is appropriate or available for use in other locations. Those who access the Service from outside the United States do so on their own initiative and are responsible for compliance with applicable local law.
This section applies only to the iOS application if and when Custos is distributed through the Apple App Store.
If you obtain the Custos application from the Apple App Store, the following additional terms apply and, in the event of a conflict, control with respect to that application:
You may not use the Service if you are located in, ordinarily resident in, or organized under the laws of a country or territory subject to comprehensive U.S. sanctions, or if you are on any U.S. Government restricted-party list. You agree not to use, export, re-export, or transfer the Service except as permitted by applicable law.
These Terms, together with the Privacy Policy, are the entire agreement between you and Custos-Keeper LLC regarding the Service and supersede any prior agreements on that subject. If any provision is held unenforceable, the remaining provisions will remain in effect. Our failure to enforce any provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, financing, reorganization, or sale of assets. There are no third-party beneficiaries except as expressly stated in Section 18. Headings are for convenience only.
