Informativa sulla privacy
This Privacy notice is a placeholder for the Beta period. The final version is pending review by legal counsel. For any urgent privacy questions, contact info@aec.codes.
This notice describes how the AEC.codes QTO add-in handles data during the public Beta. The add-in is published by MAW EOOD (Bulgaria), trading as AEC.codes.
What data the add-in stores
- Inside your Revit project: tag data in Extensible Storage and mirror Shared Parameters. This data lives in your
.rvtfile and never leaves your machine through the add-in. - Next to your Revit project: a JSON config file (
AEC_QTO_Config_<project>.json) capturing project-level QTO setup. Stored alongside the.rvt. - Catalog library: a SQLite database stored locally under your user profile.
What network calls the add-in makes
- Update check. Once per Revit session, the add-in performs
GET https://aec.codes/qto/version.phpover HTTPS to check whether a newer release is available. - License tier resolution. Once per Revit session, the add-in performs
GET https://aec.codes/qto/license_v2.phpover HTTPS to determine your account tier (Freemium or Pay). - Anonymous install statistics. Once per Revit session, the add-in performs
POST https://aec.codes/qto/telemetry.phpsending a small JSON payload with: an anonymous install identifier, the current Revit year, the list of Revit years where QTO is installed on this machine, the add-in version, and the .NET runtime version. You can opt out of this call in QTOSetup → About. - Bug reports (opt-in). Submissions you make via the in-app feedback flow or the feedback form include the content you typed plus, optionally, your email address if you provide one.
All three per-session requests carry a structured User-Agent header of the form AECCodes-QTO/<version> (Revit/<year>; dotnet/<runtime>).
What the server records
For each request from the AEC.codes QTO add-in, the server records:
- The timestamp.
- The
User-Agentstring (already part of every HTTP request). - For the install statistics POST only: the anonymous install identifier, the current Revit year, the list of Revit years installed, the add-in version, and the .NET runtime version (i.e. the payload of that POST).
The server does not record: your IP address, your Autodesk Account ID, your Windows username, your machine name, your project name, your model contents, or any other identifying information.
Why: we count active installations to (a) plan support resources, (b) prioritise bug fixes by version distribution, (c) decide which Revit years remain supported. Legal basis: legitimate interest under GDPR Article 6(1)(f).
Retention: telemetry records are retained for at most 12 months and then purged.
Anonymous install identifier
To count distinct installations (rather than just sessions), the add-in generates a random identifier on first run and stores it locally at:
%LOCALAPPDATA%\AEC.codes\QTO\install-idThis identifier is a UUID v4: a random 128-bit number with no link to your name, email, IP, or any other personal data. It is generated locally on your machine and is shared by the add-in across all Revit versions installed for the same Windows user account, so that a user with QTO on Revit 2025, 2026, and 2027 counts as one installation, not three.
You can reset this identifier at any time by deleting the file above; a new random identifier will be generated on the next add-in launch.
Under Recital 26 GDPR, identifiers that are not linked to any natural person are considered anonymous data and fall outside the scope of personal data protection. The legal basis for collecting it is legitimate interest under Article 6(1)(f) — running a sustainable software service.
Revit-year scanning
To report which Revit versions you have QTO installed in, the add-in performs
a narrow filesystem check: it tests whether the file
AECcodes.addin exists in each subfolder of:
%APPDATA%\Autodesk\Revit\Addins\Only the existence of that one file in that one directory tree is checked. No file contents are read; no other directories are scanned; no add-ins other than QTO are detected.
How to opt out of install statistics
Open QTOSetup in Revit and go to the About section. There is a checkbox labeled "Send anonymous install statistics" — uncheck it. The change takes effect immediately; no POST will be issued in subsequent sessions.
The two functional calls (update check and license tier) cannot be disabled in-app — they are required for the add-in to work. They do not record any personal data.
What the add-in does NOT do
- No personally identifiable telemetry: only anonymous installation counting via the random UUID described above. You can opt out at any time.
- No transmission of model contents.
- No third-party advertising, profiling, or data brokerage.
Data you submit voluntarily
If you submit a bug report or contact us by email, we use the information solely to triage, reproduce, and respond to your report. We retain emails for as long as we maintain a working record of the issue.
