Security

Version 1, 5 November 2026

Datlay is not open yet. This is version 1 of this page, published ahead of the launch in 2027. It describes how the service is built to be protected from the day it opens. The section on reporting a vulnerability applies now, including to this website.

Datlay holds access to the systems that run its customers' companies, and with a person's confirmation it writes to them. That makes it worth attacking. This page says what protects it, and also what it does not have yet. The measures we commit to in the contract are in Annex II of the DPA.

A workspace of your own

The least access to your systems

QuickBooks Online has no read-only access

QuickBooks Online does not offer apps an access that is limited to reading. The token that Datlay holds to read your QuickBooks company could therefore also be used to write. We cannot change that, so this is what Datlay does instead:

Every change is confirmed by a person

Each person's rights

Where your system checks each person's rights, Datlay works with that person's own login, so the person can see and change in Datlay only what that system lets them see and change. Where a system gives one company-wide access (for example QuickBooks Online and HubSpot), you decide in Datlay who may see and change what. A document Datlay has read is shown to a person, on a screen, through the API or through an assistant, only after a check of that person's rights: with the person's own login where the system checks it, and against the roles you set in Datlay where it does not.

Connection tokens

Your AI assistant

Backups and restore tests

Monitoring and incidents

Our people and our code

No AI on your data

Datlay sends your data to no AI provider, and we do not use it to train any AI model. The AI assistant your company may connect is your own, under your own terms with its provider.

What Datlay does not have yet

Reporting a vulnerability

If you believe you have found a security vulnerability in Datlay or on this website, write to security@datlay.com. The same address is published in /.well-known/security.txt. We read reports in English.

Scope

Until Datlay opens, only this website, datlay.com, is in scope. From the opening, the scope also covers app.datlay.io, your workspace at datlay.io and the Datlay connector module for Odoo.

Out of scope: other websites, including those that share our servers; our sub-processors and the vendors Datlay connects to; and reports without a demonstrated impact, such as missing headers on static pages, email authentication advice, clickjacking on pages without actions, or self-XSS.

Safe harbour

If you research in good faith and follow this section, we consider your research authorised. We will not bring a claim against you or ask the authorities to act against you for it, and if a third party does, we will say that it was authorised. Good faith means that you:

This safe harbour covers only our own systems and our own claims. It cannot bind a vendor or any other third party.
