Your formulas are yours

The standing promises, in writing

A formula library is a perfumer's working capital. Before you put yours in any tool, you deserve plain answers to the uncomfortable questions. These are ours. They are written into the Terms and Privacy Policy where it counts; this page is the readable version.

Private by default

Everything you compose, paste, or import lives in your private workspace. No other user can see it. Nothing you make is shown, listed, ranked, or shared anywhere unless you deliberately publish it.

Never training data

Your formulas are never used to train any model, ours or anyone else's. When you invoke an AI assist (such as reading a plain-language brief, drafting ideas from your inventory, writing a scent story, or suggesting a name), the text needed for that one request is sent to our AI provider to generate the answer, under API terms that exclude it from training. Your library as a whole never leaves the database, and the deterministic engine that does the real work does not learn from anything: it computes.

Export anytime

Your account page has a one-click JSON export of your formulas. There is no request form or waiting period, and it works the same on the Free tier. It is your work; taking it with you should be boring.

Delete means delete

Deleting a formula removes it from your workspace. To close your account, email [email protected] and your personal data is deleted with it, save the narrow exceptions the law requires us to keep, like billing records. The details live in the Privacy Policy.

The Formulary is opt-in, every time

Publishing an edition to the Formulary is a separate, deliberate act, never a default. When you publish, you grant a hosting license for that edition for as long as it stays published, and you can request removal. Publishing one accord shares that accord; it changes nothing about the rest of your library.

If this project ever winds down

Fragrance Engine is built and run by one person, and you should weigh that honestly. So here is the promise in writing: if the service is ever shut down, you get advance notice and a window to export everything, the full JSON of your library, before anything goes dark. Your formulas do not die with the product.
