Vulnerability Disclosure Policy

Version 0.2 · Pending legal review

Our commitment

If you think you have found a security vulnerability in anything we make or run, we want to hear about it.

We will work with you to confirm it, fix it, and disclose it responsibly. This policy says how to report, what we commit to in return, and what is in scope.

Scope

In scope — the things we actually build and run:

Out of scope:

A note on what we do not run. We do not currently operate a telemetry service, a licence-verification service, an automatic update service, or a customer portal. If you find a host that appears to be one of ours offering those, that is itself worth reporting — it is not us.

We will add to this scope as we ship things. The version and date at the top tell you how current this list is.

How to report

Send your report to security@surematters.com. We acknowledge within 1 working day, UK business hours; reports arriving outside those hours are acknowledged the next working day.

We do not currently publish a PGP key. If your finding is sensitive enough that you do not want it in plain email, say so in a short message with no detail and we will arrange a secure channel with you before you send anything.

Please include:

What we commit to

We do not currently run a bug bounty. We may later; this policy is not conditional on it.

In return, we ask that you:

Severity

Level Examples
Critical Remote code execution on the desktop application without operator interaction; compromise of a release-signing key
High A signature-verification bypass that could let altered software appear to be ours; disclosure of data held on a system we operate
Medium Cross-site scripting on our website; a logic flaw in licence validation; a denial-of-service condition on a non-customer-facing endpoint
Low Verbose errors exposing version numbers; missing security headers on non-sensitive endpoints; minor disclosure with no clear path to exploitation
Informational Hardening suggestions with nothing immediately exploitable

On the High row: in normal operation your documents are not stored on any system we operate, so the disclosure category there covers our own operational data rather than yours.

Communication

security@surematters.com is monitored Monday to Friday, UK business hours. For something critical outside those hours, put URGENT in the subject line — it is routed differently.

We are a very small company. You will deal with a person, not a queue, and we will tell you plainly if something is going to take time. We will not move a security discussion into a public channel without your agreement.

Change history

Date Version Change
2026-05-09 v0.1 Initial draft.
2026-08-12 v0.2 Correction. Scope listed a customer portal, a licence-verification service, a telemetry ingestion service and an update-distribution service. We do not run any of them, so the policy invited researchers to test hosts that do not exist. Scope now lists what we actually build and run, with a note that a host claiming to be one of those is worth reporting precisely because it is not us. The reporting section carried a placeholder for a PGP key at a path that serves nothing; it now says plainly that we do not publish one and how to send something sensitive anyway. A public researchers page and a security-advisory archive were both named as though they existed; neither does, and the references are removed. The disclosure route no longer refers to update channels that do not exist.
