Privacy notice: paper-to-order free trial
Last updated 26 September 2026
In one line: the text you paste goes to Anthropic's API and nowhere else, it is never sent to the chemical marketplaces, and your trial and everything in it are deleted after 30 days.
What we collect
- Your name, email address and organisation, entered when you start a trial.
- The time you started and agreed to this notice.
- The text you paste (experimental procedures) and the names you give your papers.
- What the tool produces from it: the compounds found, supplier offers, and your edits, approvals and choices.
- A random session identifier in a cookie, so this browser stays your trial. It is the only cookie set, and it is needed for the trial to work.
Why
To run your trial: read your procedures, find suppliers for the chemicals in them, show you the results, and keep the trial within its limits. Your name, email and organisation let the owner know who is trying the tool and follow up about it. Nothing is sold or used for advertising.

Who can see it
Only you, in your browser, and the owner of this service. The owner can open any trial's papers and results, to help you, answer your questions, and learn where the tool gets things wrong. No other trial can see your data.
Who processes it
- Anthropic reads the procedure text you paste, through its API, to pick out the chemicals. Under Anthropic's Commercial Terms Anthropic may not train models on this content. Anthropic says it deletes API inputs and outputs within 30 days, and may keep them longer where the law requires or its usage policy is breached (Anthropic's retention page).
- Railway hosts the application and its database.
- MolPort, ChemSpace and Mcule, chemical marketplaces, are sent the chemical's name, structure and amount when a supplier lookup runs. Your name, email and procedure text are not sent to them.
- When no marketplace lists a chemical, the lookup may search the web for suppliers, which also goes through Anthropic's API, and may fetch suppliers' public pages through Firecrawl. Only the chemical's name and the supplier page addresses are sent, never your details or pasted text.
Nothing else. The typefaces, stylesheets and images this site uses are served from this site, so loading a page tells no one but us that you visited.
What allows us to
Running your trial, and keeping it within its limits, is our legitimate
interest in showing you the product you asked to try: you gave us your details
in order to be given a trial, and we use them for that and to follow up about
it. Sending your pasted text to Anthropic is the one thing we do not rest on
that: it is what the tick-box beside this notice is for, and the time you
ticked it is recorded as privacy_accepted_at. Withdraw it by
deleting your trial, which stops anything further being sent; it cannot recall
what has already gone (see "Deleting it sooner"). We do not sell anything, we
do not profile anyone, and there is no automated decision here with a legal
effect on you.
Your rights
You can ask us for a copy of what we hold about you, to correct it, to delete it, to have it in a portable form, and to object to our using it at all. Write to siyun_cao@outlook.com and we will answer within 30 days — usually the same week, because there is one person and a small database. Deleting a trial is the one you can do yourself, immediately, without asking. If we get it wrong, you can complain to a data protection supervisory authority; in the UK that is the Information Commissioner's Office.
Where it goes
Three of the processors above are outside the UK and the EEA: Anthropic (United States) reads your pasted text, Railway (United States) hosts the application and its database, and Firecrawl (United States) fetches suppliers' public pages. Each transfer is made under the European Commission's Standard Contractual Clauses, as incorporated by those companies' own data processing terms, together with the UK Addendum where UK law applies. The data processing agreement lists them with what each one receives.
If something goes wrong
If personal data here is lost or exposed, we will tell the relevant supervisory authority within 72 hours of becoming aware of it, and tell you directly, at the address you gave, if the breach is likely to be a high risk to you. We will say what happened, what was affected and what we did, rather than that "an incident occurred".
How long
Your trial and everything in it are deleted 30 days after you start. Your email address is kept after that as a keyed hash: we can check whether an address is already on the list, but neither we nor anyone holding a copy of the database can read the list back as addresses. That entry is kept for 12 months and then deleted, and an entry for a trial that never got as far as reading a paper is deleted after 24 hours. Write to siyun_cao@outlook.com to have your address released sooner. A count of how many trials started each day is kept, with nothing identifying anyone. Supplier search results for a chemical are cached on the server for up to 7 days so the same search is not paid for twice; the cache holds the chemical and its offers, not who asked. To stop one person taking every trial place, a keyed hash of your network address and the date is kept for the day you start, and deleted after it.
Deleting it sooner
Press Delete my trial now in the app. That removes your details, your pasted text and all results from this app straight away (the shared supplier-search cache above is not linked to you and expires on its own). It cannot reach the copy of your pasted text already sent to Anthropic: Anthropic deletes that within 30 days, and keeps it longer only where the law requires or its usage policy is breached. The owner can also delete a trial on request.
