ZeroMark is inbox zero for bookmarks. This page explains what we store, where it lives, and what we do not do with it.
Who operates this
ZeroMark is operated by Tellurave LLC.
What we collect
If you start a trial: the email address you submit, which page you signed up from, and when you confirmed it. Nothing else until you connect an account.
If you connect : your email address, the access tokens that let us read your bookmarks (encrypted at rest), the bookmarks and likes you sync or import, any notes you write, and your triage and digest history.
If you subscribe: billing is handled by Stripe. We store their customer and subscription identifiers, status, and the paid-through date so we know whether access should stay open. We do not store your full card number. See Stripe's privacy policy.
Session cookie: one signed, HttpOnly cookie so you stay signed in. No advertising or third-party tracking cookies, and no analytics that follow you off the site.
What we can and cannot touch on
Read-only. The connection can pull your bookmarks and likes; it cannot post, follow, message, or change anything on your account. You can revoke it from your settings at any time, and ask us to delete what we already hold.
Where it lives
On managed cloud infrastructure, in an access-controlled database reachable only by the app, encrypted in transit. Trial and digest email goes out through a third-party email provider. Payments go through Stripe.
How AI is used
Once you connect an account, the text of your saves is sent to a third-party AI provider so it can be classified, summarized, and answered against in chat. That runs on a tier where your content is not used to train anyone's model. A signup email on its own is never sent to an AI provider.
What we do not do
We do not sell your data or use it for advertising.
We do not put other people's addresses on your email, and we do not batch sends via CC or BCC.
What the Mirror learns about your reading stays yours. It is never pooled across people.
Submitting your email alone does not connect your account. App access starts after you confirm and begin the trial, or subscribe.
Contact and deletion
Ask us to delete your account and everything tied to it goes, including your saves, your notes, and your tokens. Billing history may remain with the payment processor as required for accounting. Email [email protected]. Ask a question or request deletion that way.
