No other business can see your data. Ever. Here is the actual mechanism rather than a promise.

How it is enforced#

Rennt is multi-tenant — many rental businesses share one system. Every table is protected by row-level security, a rule enforced by the database itself that filters every single query by your business ID.

That distinction matters: it is not application code that could have a bug and leak. The database refuses to return another business's rows even if the code asked for them.

We attack it on purpose#

We run adversarial tests regularly: authenticate as one business and deliberately try to read another's bookings, customers and products. It returns nothing, every time. That check runs as part of our automated audit, not as a one-off someone remembered to do.

Your customers' card details#

They never touch Rennt at all. Cards go straight to Stripe, and the money goes straight to your bank. We do not store card numbers because we never receive them.

Your data is yours#

Export it any time — products, bookings, customers, all as CSV. No lock-in, no "contact sales to export".
