The fine print, in plain words.
By using Esta you agree to these terms. They’re short because Esta keeps your records on your device, and anything you share is encrypted before it reaches our servers.

What Esta is
Esta is a tool for keeping track of properties, tenants and leases, rent, and expenses shared with others. It runs in your browser and stores your records on your device. With optional team access you can share a workspace with other people; shared records are encrypted on your device and synced through our servers. See the privacy page for how your information is handled.
Your records are your responsibility
- Your data lives only in the browser on your device. Clearing browser data, losing or resetting the device, or using private browsing can remove it. Make regular backups from Settings.
- If you forget your encrypted vault password or backup passphrase, the data it protects can’t be recovered — by you or by us.
- You’re responsible for the accuracy of what you enter, and for having the right to store and share information about other people, such as tenants and co-owners.
- If you forget your team password, the backup of your encryption keys can’t be opened. Keep it safe, and keep access to a device that’s signed in.
Team access
- Keep your team password private. You’re responsible for what happens under your account.
- The owner and co-owners of a workspace decide who joins and what role they have. Invite only people you trust: an editor can change and delete shared records, and anyone you remove keeps what was already on their device.
- We may suspend team accounts that are used to break these terms or the law, or that put the service or other users at risk.
Not professional advice
Esta’s figures — rent schedules, late fees, balances, splits, yields and returns — are calculated from what you enter, to help you stay organised. They aren’t financial, tax, accounting or legal advice. Check important decisions with a qualified professional.
Fair use
Use Esta only for lawful purposes. Don’t try to disrupt the service, get around its security, or use it to store or share content you don’t have the right to.
Availability and changes
We may improve, change or pause parts of Esta, for example during maintenance. Because Esta works offline once it has loaded, a copy you’ve already opened or installed usually keeps working while the website is unavailable; shared workspaces catch up when the service is back.
No warranty
Esta is provided “as is”, without warranties of any kind. To the fullest extent the law allows, we aren’t liable for lost data, lost profits or other indirect losses arising from your use of Esta. Some places don’t allow these limits, so they may not all apply to you.
