Privacy

Last updated November 11, 2026

Atesto collects what a walk needs and nothing more. We do not sell it and we do not use it for advertising. You can ask us to delete it.

What we collect, and why

The place

The address you type, the number of bedrooms and bathrooms, and the rooms you tap. They are printed on your report.

Your photographs

Up to 120 a walk. Each one is resized on your phone before it is sent, so Atesto never receives the full-size original. They are sealed, read, and printed in your report.

Times

When each photograph was taken by your phone’s clock, when Atesto received it, and your time zone. They date the report.

Location, if you allow it

One reading from your phone, printed on your report with its accuracy and the photograph it came with. Atesto tries for it at up to three of your photographs, then stops. If your phone gives no reading, the report says none was recorded. If you say no, the report says location was not granted and nothing else changes.

Your email address

It is where your sample report and your report are sent, and it is how the free sample is kept to one per person. We write to you about your own walk and nothing else.

Payment

Stripe takes the payment. Your card details go to Stripe and never reach Atesto. Atesto learns your email address, the amount, and that the payment went through. Stripe also sees the address of the place, as the description of what you bought.

Cookies, and daily limits

Atesto sets one cookie that tells one phone from another, so that one visitor cannot use up the service for everyone. For the same reason it counts walks and uploads per network each day, using a scrambled form of your network address that changes every day. Atesto’s own records do not keep the address itself. Our host’s request logs do, for a short time, as any web host’s do. A phone that opened Atesto from an invite link also carries a cookie that remembers the invite.

Visits

Page views and a few steps of the walk, such as “a sample was shown”, are counted with Vercel Web Analytics. It uses no cookies and the counts are not tied to you. It records the page, the site you came from, your browser and device type, and the country, region and city the visit came from.

On your phone

Your photographs and your walk in progress are also kept in your browser on your phone, and they stay there after they upload. Clearing the browser’s site data removes them.

Who else handles it

Each of these handles your information only to do its part.

Vercel

Hosts Atesto, stores the photographs and reports, and counts visits.

Anthropic

Provides the AI model that reads your photographs to write the report’s notes. Its terms do not allow it to train its models on them.

Stripe

Takes payments.

Resend

Delivers Atesto’s email, including your report as an attachment.

A timestamp authority

DigiCert, GlobalSign or SSL.com stamps the time of the seal. It receives only the fingerprint of your sealed set, a string of letters and numbers. It never receives a photograph, an address or an email.

We do not sell your information and we do not share it for advertising. We hand information over only if the law requires it.

Your report link

Anyone with the link to your report can open it: the address, the photographs and the notes. The link is not listed anywhere and cannot be guessed. Treat it like the report itself.

Your walk link

The link in your sample email opens your walk on any phone or browser for 30 days, so you can finish it and get your report. Anyone who has that email can do the same.

How long we keep it

A walk that is never paid for: 30 days, then it is deleted. A paid report and its sealed photographs: 24 months, then they are deleted. They are kept that long because a report can only be checked against the sealed photographs while they exist. Stripe keeps its own record of a payment for as long as the law requires.

Deleting yours

Write to hello@tryatesto.com from the email address you gave Atesto, with your report’s record number if you have it. We delete the photographs, the report and your email address. A deleted report cannot be opened or checked again.

Children

Atesto is for adults. It is not meant for anyone under 18.

Changes

When this page changes, the date at the top changes.
