Privacy & local storage.

Who is responsible

Perfume Bench is operated by Known by One, LLC, the controller for personal information we process to run this site and respond to enquiries. Contact contact@knownbyone.com with “Perfume Bench privacy” in the subject.

Registered address: 131 Continental Dr, Suite 305, Newark, Delaware 19713, United States.

Formulas, imports and study records

Calculator inputs, material searches, CSV and JSON imports, and journal entries are processed in your browser. Selecting an import file does not upload it. The tools do not send this content to our server or an AI provider.

The formula builder, blotter journal and course use browser local storage to remember working drafts, named formulas, studies and lesson progress. Copies passed between the formula, batch, pricing and journal tools are also stored locally. CSV import saves the previous valid draft as a separate named formula before opening the imported draft.

These local records have no automatic expiry. They remain until you or your browser remove them, or a tool replaces a working record. We cannot retrieve, synchronize or remotely delete these records for you. Private browsing, browser cleanup, changing devices or visiting a different domain can remove or hide them.

Hosting and website requests

Vercel hosts the site and delivers its pages and files. Serving a page involves technical information such as an IP address, requested URL, time and browser information. Vercel may process request and security records to deliver the site, diagnose faults and prevent abuse. This is separate from the formula and journal content processed locally.

Hosting records are subject to the provider’s service configuration and retention practices. They are not covered by our statement that formula records stay in your browser. See Vercel’s privacy notice for information about its processing.

If you email us

We receive your email address, message and anything you choose to attach. We use them to answer your enquiry, investigate a reported problem, handle a rights request or resolve a dispute. Our email service provider processes those messages for delivery and storage. We do not add support contacts to a mailing list.

We retain correspondence for as long as needed to deal with the enquiry and related follow-up, or to meet legal obligations and establish or defend a claim. The purpose of the correspondence and any continuing obligation determine that period. You can ask us about or request deletion of a particular message using the contact above.

Cookies, tracking and browser storage

We use two analytics services to see which pages and tools people use: Google Analytics 4 (Google LLC) and Microsoft Clarity (Microsoft Corporation). They record pages viewed, the tool actions we have chosen to count (editing or saving a formula, picking a listed material, loading a study, exporting a file, importing a CSV, sending a formula to another tool, marking a lesson complete; these record that the action happened, not what you entered), device and browser type, and an approximate location derived from the IP address. Clarity also records how a page is used (clicks, scrolling and pointer movement) as session replays and heatmaps; text typed into fields is masked before it leaves your browser. The contents of your formulas, journal entries and imported files are not sent to either service.

These services set first-party cookies (Google: _ga and _ga_*; Clarity: _clck and _clsk). If your browser’s time zone is in Europe, neither service loads until you choose Accept in the cookie banner; elsewhere they load by default. You can change your choice at any time with “Cookie settings” in the footer. Choosing Reject stops the services, removes their cookies and reloads the page. Google Analytics event data is kept for 14 months. We have not enabled advertising features in either service. See Google’s privacy policy and Microsoft’s privacy statement for how each provider processes data.

There is no account system, payment collection or advertising script. Fonts and site images are served with the site. Local storage supports the save, recovery, transfer and progress features described above; it is not used to build advertising profiles.

You can block or clear site storage through your browser settings. Saved-work and progress features will then be unavailable or unable to retain changes.

Purposes, sharing and international processing

Where UK or European data protection law applies, we rely on legitimate interests to deliver and secure the website and respond to enquiries: operating a working service, resolving faults and answering people who contact us. Analytics cookies for visitors in Europe are set only with your consent, given through the cookie banner; elsewhere we rely on legitimate interests in understanding how the site is used, with the same “Cookie settings” control to object. We may also process information where necessary to comply with a legal obligation. You may object to processing based on legitimate interests.

We do not sell personal information or share it for cross-context behavioral advertising. Hosting and email providers process information for the services described above. Information may also be disclosed when required by law or necessary to establish or defend legal rights.

The operator is in the United States and service providers may process information in other countries. Where applicable law requires a safeguard for an international transfer, that requirement still applies. Contact us for information about the arrangements relevant to your request.

Your choices and rights

Depending on the law that applies to you, you may have rights to access, correct, delete or receive a copy of personal information we hold, restrict its use, or object to processing. Email the contact above to make a request. We may need proportionate information to verify it. These rights are subject to applicable exceptions, including legal retention requirements.

You may also complain to the data protection authority where you live or work, where applicable. In the UK this is the Information Commissioner’s Office; in the EEA, contact your local supervisory authority.

For records held only on your device, export anything you want to keep, then clear this site’s storage in your browser. Deleting a named formula does not erase its working draft or copies attached to journal studies. Browser exports create separate files on your device; clearing site storage does not delete those files.

External links and changes

Supplier references and profile links open other websites, whose own privacy practices apply. Sending us an email also involves your email provider. This notice covers Perfume Bench; it does not describe every service operated by Known by One, LLC.

We will update this page if our data practices change. New features involving accounts, tracking or sending tool inputs to a server would need to be explained before they are used. The date above records the latest update to this notice.
