Security

What we can evidence, and what we cannot

A security page is quickly filled with badges. This one says what actually happens technically, and where we deliberately promise nothing.

  • Encrypted in transit

    The connection between your device and the cloud is encrypted. The site also sets HSTS, a content security policy and prevents embedding in other sites.

  • Tenants are separated

    Your data belongs to a tenant. Separation is enforced server-side on every request and additionally secured at database level through row-level rules. A hidden menu is not security, so we check on the server, not in the browser.

  • Secrets are stored encrypted

    Credentials you enter, for email sending or a shop, are encrypted before being stored. A look into the database does not reveal them.

  • Locked, not deletable

    A locked invoice is never changed and never deleted. Corrections run through cancellation and reissue. Every action is recorded with a timestamp.

  • Per-person permissions

    You invite staff by email and give each exactly the areas they need. Access can be time-limited. Only owners and full-access admins see team management.

What we deliberately do not claim

  • No statement about server location. Where and by which processors your data is handled is set out in the privacy policy, and only there.
  • No backup promise. Until we have verified the scope, we do not promise it.
  • No full offline operation. A local cache bridges short connection drops, nothing more.
  • No certification. There is no GoBD certification for software, and we do not pretend otherwise.

Applies to every plan

Encryption, tenant separation, locking and the audit trail are not a plan question. They apply in the free Start plan just as in Business. Team roles and time-limited access come with Business.

Write your first invoice.

The Start plan is free with no time limit. No bank connection, no installation, no credit card.
