How licenses are counted
The number of licenses is the number of machines (PCs) that run the software. A machine can be released from the "Devices" section of the customer portal when replacing it. Usage is visible in the customer portal at any time.
Renewal
- Credit card: renews automatically every year. Stop auto-renewal or change the quantity from "Manage billing" in the customer portal.
- Invoice billing: no auto-renewal. We email you 30 and 7 days before expiry, and you can request a renewal from the customer portal.
Security and data handling
DMP files are parsed entirely on your PC. Neither the file contents nor any extracted data are sent to our servers.
Information sent by the license check and usage record at startup (paid licenses only)
- License key
- Machine identifier (irreversible hash)
- IP address (used only to determine the country)
- OS and application version
- Whether the machine is joined to an organisation's domain (Active Directory)
- Time of the check-in and cumulative number of check-ins
Types of network activity and when they occur
The application performs only the five kinds of network activity below. Only the license check at startup is required; everything else either has no effect on operation when blocked or happens only when you choose to use it. The contents of DMP files are never sent unless you explicitly attach a file to an error report.
| Feature | When | Host | What is sent |
|---|---|---|---|
| License check | At startup (when a license is registered) | api.odv.dev | License key |
| Usage record | Once a day at startup (paid licenses only; the trial version sends nothing) | api.odv.dev | The items listed under "Information sent" above |
| Update check | At startup (except the Microsoft Store edition) | api.github.com → github.com | Nothing is sent; the application only fetches the latest version number. The installer is downloaded from github.com only if a newer version exists and you choose Yes. There is no forced update. |
| Error report | Only when you submit one from Help > Error Report | report.odv.dev | The title, description and optional contact you enter, plus environment details (application, OS and .NET versions, CPU architecture, locale, DPI, memory usage, screen resolution, dump format and size, and the most recent stack trace). File names, computer names and user names are not sent. The dump file itself is sent only if you tick "Attach dump file" (off by default, up to 50 MB). |
| Oracle Instant Client auto setup | Only when you run "Auto setup" in the export options and confirm with Yes | oracle-dl.odv.dev → download.oracle.com | Nothing is sent; the application only fetches the download URL list and the Oracle Instant Client ZIP files. |
This list matches the application source code, which is published on GitHub and can be inspected by anyone. View the source code
Hosts to allow (firewall / proxy)
All traffic is HTTPS (TCP 443) and outbound from the application only; there are no inbound connections. The Windows system proxy settings are used.
| Host | Type | Purpose |
|---|---|---|
| api.odv.dev | Required | License check and usage record (application) |
| odv.dev / www.odv.dev | Browser | License check for older versions (forwarded to api.odv.dev), customer portal |
| api.github.com | Optional | Update check (at startup; blocking it does not affect operation) |
| github.com / objects.githubusercontent.com | Optional | Installer download (browser, and when you accept an update) |
| report.odv.dev | Optional | Sending error reports (only when you choose to) |
| oracle-dl.odv.dev / download.oracle.com | Optional | Oracle Instant Client auto setup (only when you choose to) |
- If the server cannot be reached (offline, blocked by a proxy, or an outage), the application still starts and the license is not treated as revoked. A license is treated as revoked only when the server explicitly responds that it is invalid.
- License files are RSA-signed and the application verifies the signature offline.
- Published usage statistics are aggregate figures from which no individual or organisation can be identified. See the privacy policy for details. Privacy policy
