Privacy policy
What data we receive, why, how long we keep it and how to ask for its deletion. Your messages never reach us.
Effective from: 1 November 2026.
1. Who is responsible for the data
The controller of personal data is ENGINEERIO S.R.L., tax ID RO 50410082, registered at Șos. Olteniței 246, Sector 4, Bucharest, Romania. For any question about data, including access or deletion requests: contact@klasor.app.
2. What data we process
| Data | Source | Purpose | Legal basis (GDPR) |
|---|---|---|---|
| Mac ID (a hash computed from the hardware ID and the product name; not the serial number, and it cannot be correlated across products) | The application, when checking the license or during the trial | To tie the license or trial to that Mac and enforce the Mac limit | Performance of the contract, Art. 6(1)(b); legitimate interest (preventing abuse), Art. 6(1)(f) |
| Application version | The application | New-version notices, support | Art. 6(1)(b) |
| IP address and time of the request | The application's or the browser's connection | Security: limiting repeated attempts and detecting abuse | Legitimate interest, Art. 6(1)(f) |
| Number of messages processed during the trial (the number only) | The application, during the trial | To apply the trial limit of 1,000 messages | Art. 6(1)(b) |
| Holder's name and e-mail address | From you, when you order | Issuing the license, sending the key, support | Art. 6(1)(b) |
| Billing details (company or name, address, tax ID) | From you, when you order | The invoice and accounting obligations | Legal obligation, Art. 6(1)(c) |
| Support messages and the diagnostics report you send | From you | Solving the problem | Art. 6(1)(b) and 6(1)(f) |
| Web server logs (IP, time, page, browser) | Visiting the site and the application's requests to the license server | Operation and security | Legitimate interest, Art. 6(1)(f) |
3. What we do NOT process
Your messages, subjects, recipients, folders, the contents of exports and your Mac's name never reach us. Klasor works locally, on your Mac. The license server sees none of it. Freeing space, restoring, searching and viewing messages in your exports also happen locally on your Mac and send nothing to us. We do not use data for advertising, we do not sell it and we do not build profiles.
4. Diagnostics and error codes
Errors in the application have a code (for example KL-102). You generate the diagnostics report and send it yourself, after seeing it. It contains versions, states, numbers, error codes and the Mac ID (first 8 characters). It does not contain messages, subjects, folders, paths or e-mail addresses.
5. How long we keep data
| Data | Duration |
|---|---|
| IP address in the request-limiting table | Deleted automatically after 24 hours. |
| IP address in the license server's security logs | At most 90 days; deletion is automatic, daily. |
| Mac ID and trial counter | At most 12 months after the trial ends (needed so that an ended trial cannot be restarted). |
| Holder, e-mail, activations | While the license is valid, then 5 years from the end of the financial year in which the document was issued (Accounting Law no. 82/1991, art. 25) for billing data; the rest is deleted at your request. |
| Web server logs | At most 90 days. |
| Support messages | At most 90 days after the request is resolved. |
| Data on your Mac (configuration, history, log, the search index of your exports) | Stays with you until you delete it (Reset or uninstall). More: what Klasor stores on your Mac. |
The periods above follow the storage limitation principle (art. 5(1)(e) GDPR): we keep data only as long as the purpose needs it. For billing documents, the period comes from the Romanian Accounting Law no. 82/1991. The law sets no specific period for security logs; we chose a short one, which the server applies automatically.
6. Who receives it
The license server and the site run at VISIO CONSTRUCTION WORKS S.R.L., Romania, our hosting provider, acting as processor. Billing details go to our accountant and, where applicable, to authorities that request them by law. We do not transfer data outside the European Economic Area except with the safeguards GDPR requires.
7. Your rights
You have the right of access, rectification, erasure, restriction of processing, portability and objection, and the right to withdraw consent where processing is based on it. To have your data deleted, write to contact@klasor.app; we delete the data tied to your license and your Macs' IDs, except documents the law requires us to keep (the invoice). We answer within one month.
If you are unhappy with the answer, you can lodge a complaint with the National Supervisory Authority for Personal Data Processing (ANSPDCP).
8. Cookies and tracking
The site uses no cookies, no third-party tracking or analytics tools, and no content loaded from other sites. The only information kept in your browser is your language choice (klasor-lang, in local storage), strictly for the site to work; it does not leave the browser and we do not read it. That is why we show no cookie banner. Statistics rely only on web server logs.
9. Security
The application talks to the license server over HTTPS, and the server's responses are digitally signed and verified by the application. The license key is stored on the server only as a hash. Administrative access to the server uses SSH keys, and the server's data has encrypted backups.
10. Changes
If we change this policy, we publish the new version here with its effective date.
