Cyzica is a lab notebook. It holds your working records, so this page says plainly what is stored, who can reach it, and what happens when you want it gone.
Your name, email address, and anything optional you add to your profile — a job title, a phone number, a colour. Your password is never stored; only a hash of it, which cannot be turned back.
Then the work itself: labs, projects and their milestones, protocols and every version of them, calculators, genes, experiment records, controlled-substance logs, calendar events, the reminders you write yourself, and any files you upload.
An audit trail records who did what — created a protocol, logged a dose, moved a project — so a lab record can be traced.
If you send feedback, the message is kept along with your name and the page you were on, so it can be acted on and answered. Nothing else about where you have been is recorded.
Nothing is public. Every read is checked against one permission rule: your own work is yours, and members of a lab can see what has been shared with that lab. Somebody who is in no lab with you cannot see anything of yours, including whether it exists.
Uploaded files are stored privately and are never served from a guessable address — every download is checked the same way.
If you turn on the optional “show when I am around” setting, people you work with can see whether you are online. Turning it off stops it being recorded at all, not merely shown.
Email — verification links, password resets, notifications — is sent through Resend. Your address and the message go to them so it can be delivered. The application is hosted by Vercel and its data is held by Neon, both in the United States. Nothing is sold, and there is no advertising or third-party tracking of any kind.
Everything you have written can be downloaded at any time, without asking anybody: Settings → Take your work with you. Protocols come out as documents and the rest as spreadsheets, both readable without Cyzica. A controlled-substance log is exported from the drug’s own page, with its running balance.
Write to privacy@cyzica.com and ask. There is no self-service delete button yet, so this is a human doing it — say so plainly rather than pretend otherwise.
Two things cannot be deleted, and this is deliberate: entries in a controlled-substance log, and the audit trail. Those are regulatory records. A mistake in them is corrected by a further entry that references the original, with both left visible — which is what makes them worth anything. Removing your account removes your access and your personal work; it does not rewrite a logbook your lab relies on.
If this page changes in a way that affects what happens to your work, you will be told by email rather than left to notice a date.
