Herald is operated by Maverick Systems. This page says what Herald keeps, why, and for how long, for three kinds of people: those who receive email sent through Herald, the people who use Console, and visitors to this site.
If you received an email sent through Herald
The product that emailed you (Mentor, Sidekick, Hallelo or another) decides what it sends and to whom; Herald carries the mail for it, on its instructions. To see, correct or delete what it holds about you, ask that product. Herald gives every product the tools to export everything held about you and to erase it.
What Herald keeps for each product:
- Your address, and what happened to each email: sent, delivered, bounced, or reported as spam.
- Opens and clicks, only where the product has switched them on.
- The email’s content, sealed under the product’s own key, for as long as the product chooses (30 days unless it says otherwise; some keep none at all).
- Your choices: which topics you subscribed to, how and when you agreed, and whether you unsubscribed.
- A suppression record if you unsubscribed, bounced or complained. If you ask a product to erase you, a one-way hash of your address stays, so you’re never emailed again by mistake; nothing else does.
Herald never sells or shares this information, never combines one product’s data with another’s, and never uses it to advertise.
If you use Console
Herald keeps your name, your email address, your passkeys’ public keys (never anything that could sign in as you), your sessions, and an audit log of what you did in each project. It uses them to let you in, to keep your projects secure, and to show your team who did what.
If you visit this site
No cookies, no analytics, no tracking pixels and no third-party scripts. Our servers keep ordinary access logs (the address you came from, your browser and the page asked for) to keep the service secure, with secrets removed from them; we don’t use them for anything else.
Where it’s kept
On Maverick Systems’ own servers, encrypted at rest. Mail goes, of course, to the recipient’s own email provider. Google Postmaster Tools sends us figures about how Gmail received our mail; nothing about you goes the other way.
