Terms of service

Last updated 26 October 2026

Draft. This is a placeholder that shows the shape of the final document. It has not been reviewed by a lawyer and is not yet in force.

These terms are between Yesna (“we”), which provides Petra Platform, and the estate or estate management company that subscribes to it (“the estate”). Residents and guards use Petra Platform through the estate.

[To confirm: the company’s registered name and address, and the governing law and courts.]

The service

Petra Platform provides apps for residents and guards, a web app for the estate office, and software for gate controllers. We host and maintain the service and aim to keep it available around the clock. Gates are designed to keep working without the internet, but we do not guarantee uninterrupted service, and the estate remains responsible for the physical security of its gates.

The estate’s responsibilities

  • Keep admin accounts secure, give admins only the permissions they need, and remove those who leave.
  • Have the right to add residents’, guards’ and visitors’ data to Petra Platform, and tell them how it is used.
  • Use Petra Platform lawfully, and not to harass, track or discriminate against anyone.
  • Install and maintain any gate hardware, or have it installed by someone competent.

Fees

The estate pays the subscription for its plan, per occupied property per month (or yearly), plus messages beyond the plan’s allowance, as invoiced. Invoices are due seven days after issue. If an invoice is more than 14 days overdue, changes in the web app are paused until it is paid; gates, guards and residents are not affected.

Residents’ payments of estate dues go to the estate’s own account through the payment gateway. We do not hold them and are not a party to them.

Data

The estate owns its data. We process it to provide the service, as described in the privacy policy. When the estate leaves, it can export its data, after which we delete it within a reasonable period, except where the law requires us to keep it.

Liability

[To confirm with counsel: limitation of liability, indemnities and warranties.]

Ending the subscription

The estate can cancel at the end of any billing period. We may suspend or end the service for serious breach of these terms, after notice where possible.

Changes

We will give notice of material changes to these terms before they take effect.
