Privacy
Last updated 8 October 2026
The short version. Memari stores the planners you build and, if you make an account, your sign-in details sit with our authentication provider. If you point it at a calendar, it reads that calendar and never writes to it. If you order a printed book, we keep what is needed to make and deliver it, and share it only with the printer that makes it and the company that takes the payment. There is no advertising, no tracking, no analytics of any kind, and nothing is sold or shared for marketing. You can use it without an account at all. The detail below is what actually binds.
Memari Studio is run by Memari LLC (“we”, “us”). This page covers memari.studio and the app on it.
What we hold
What you make. Your journals: their names, the term you set, the pages, and every module on them — including whatever you write inside those modules. A planner is a personal thing, and its contents can be too. We treat everything you type as yours and private. It is stored so we can show it back to you and print it; we do not read it, mine it, or train anything on it.
Events you write. An event on a page is stored with its title, its start and end, whether it repeats, and which of your calendars it belongs to. Delete one you typed and the record is removed, not hidden.
If you subscribe to a calendar. You can give Memari the address of a calendar feed — the secret .ics address Google, Apple and Microsoft each offer. We store that address, because we need it to read the feed again, and we fetch the feed from our server rather than from your browser. It is a secret: we never show it back to you, never put it in an error message, and never send it to anyone else. We read the feed while you have the journal open, at most every fifteen minutes, and we store the events it contains — their titles, times and repeat rules, and the identifiers the provider uses, so that reading it again updates what is there instead of duplicating it. We do not write anything back to your calendar. Remove the subscription and the address and its events go with it.
An event removed at the far end leaves a marker here recording that it was removed, so the next read does not bring it back. That marker keeps the event’s details until the subscription is removed, which deletes them.
If you sign in. Authentication is handled by Clerk. They hold your email address, your name if you gave one, and whatever your provider returns if you sign in with Google. We do not copy any of that into our own database, except your email onto an order if you order a printed book (below). Otherwise our records identify you only by the opaque account id Clerk issues.
If you continue as a guest. No account, no email, no name. Your browser is given a random identifier — 128 bits of randomness, signed so it cannot be forged or guessed — stored in a cookie that JavaScript on the page cannot read. That identifier is the only thing connecting you to the journals you make. Clear the cookie and they are unreachable; see how long we keep them below.
Technical records. Our host keeps ordinary server logs, which include IP addresses and request details, for security and for working out why something broke. We do not combine them with your journals to build a profile.
If you order a printed book. We keep the order: the name, address, phone number and email you give for delivery, what you ordered (the journal, the days, the binding, the shipping) and what it cost, and the two files the book is printed from — its pages and its cover. If you turn auto-renew on we also keep a reference to the card Stripe saved for it; the card itself never reaches us.
What we do not do
- No advertising, and no advertising identifiers.
- No analytics and no tracking — not our own, and no third-party measurement script. There is no Google Analytics, no tag manager, no session recorder, no error reporter.
- We do not sell your information, and we do not share it for anyone else’s marketing.
- We do not use what you write to train machine-learning models.
- We do not write to, change or delete anything in a calendar you subscribe to. Reading is all we do.
Cookies
Memari sets four cookies of its own. All are first-party, none is used for advertising or measurement, and every one exists to make the app work or to put it back the way you left it.
memari-guest— your guest identifier, if you use the app without an account. Signed, and marked so page scripts cannot read it.memari-journal— which journal you had open, so the app reopens it.memari-open— which set of pages you were last editing.memari-viewport— your zoom and scroll position, so the canvas is where you left it rather than reset.
If you sign in, Clerk also sets its own cookies to keep you signed in. See Clerk’s privacy policy.
Who else processes it
We use these companies to run the service. They act on our instructions.
- Vercel — hosting, and the server logs described above.
- Neon — the database your journals are stored in.
- Clerk — accounts and sign-in, for people who choose to have one.
- Stripe — payment for printed books. You give your card to Stripe on their page, not to us. They receive your name, email and the order’s amount, and save your card only if you turn auto-renew on.
- Resend — the emails about your orders: that a book is printing, has shipped, or will renew. They receive your email address and what the email says, and nothing else.
- Lulu — printing and posting books. For each order they receive the delivery name, address, phone number and email, and the book’s files, and pass the address to the carrier that delivers it.
- BookVault (Printondemand-Worldwide, in the UK) — printing and posting metal wire-o books. For each such order they receive the delivery name, address, phone number and email, and the book’s files, and pass the address to the carrier that delivers it and, for a book going abroad, to customs.
How long anything is kept
- Guest journals are deleted after 30 days without being opened. Saved pages and saved modules belonging to a guest go when that guest has no journals left. This is not a threat to get you to sign up — it is how we avoid keeping work nobody is coming back for. If you want a journal to last, sign in and it comes with you.
- Account journals are kept until you delete them. Deleting a journal removes its pages and modules.
- Calendars are kept until you remove them. They belong to you rather than to one journal, so removing a journal leaves them; removing a calendar deletes its address and every event on it. A guest’s calendars go when their journals do.
- Orders are kept as a record of the sale, for as long as tax and accounting rules require. A book’s files are deleted a year after it is delivered or cancelled — long enough to reprint one that arrives damaged — and the files of a checkout that was never paid are deleted after a month.
- A library search is not kept. The ZIP code or town you type on the Print it yourself page finds the nearest libraries in a list we hold, and is then discarded. No map or places service is asked.
- Server logs are kept for a short period by our host, on their schedule.
Exports and printing
Exporting a PDF builds the file on our server from the journal already stored there and hands it straight back to your browser. The file is not kept and not sent anywhere else. Ordering a printed book is different: its files are kept with the order and fetched by the printer to print it, as described above.
Your choices
- Use the app as a guest, and give us no personal details at all.
- Delete any journal, saved page or saved module from inside the app.
- Turn a calendar off for one journal without removing it, or remove it entirely, under Page Settings → Calendars.
- Export your work as a PDF at any time.
- Delete your account and everything in it yourself, under Account → Data & account: journals, saved pages and modules, calendars, settings and your sign-in. Records of printed books are kept as described above, with auto-renew turned off.
- Ask us for a copy of what we hold about you, or ask us to delete it, by writing to hello@memari.studio. If you are in the UK, EU or California you have rights over your personal information under local law, and we will honour them wherever you are.
Children
Memari is not aimed at children under 13, and we do not knowingly collect their personal information. If you believe a child has given us any, write to us and we will remove it.
Changes
If this page changes in a way that affects what we do with your information, we will change the date at the top and, for anything significant, tell account holders directly.
