TSNLE Privacy Policy
Last updated: July 5, 2026
1. Data Controller
Responsible for TSNLE and its data processing:
Stefan Lohmaier
Weitlstr. 103
80935 München
Germany
Email: admin@slohmaier.com
Website: slohmaier.com
A data protection officer has not been appointed; there is no obligation to appoint one under Art. 37 GDPR or § 38 BDSG.
2. Summary
TSNLE’s core features run entirely offline. Video editing, transcript navigation, timeline operations, and export never transmit your media, transcripts, or project data — none of this data leaves your device unless you explicitly enable an optional cloud AI engine (see section 9).
However, TSNLE is licensed software. License activation and periodic validation contact our licensing service at lic.slohmaier.com. This page explains exactly what is sent, what is stored, and on what legal basis.
- No telemetry, analytics, or crash reporting
- No tracking SDKs or advertising libraries
- Network access is limited to license activation/validation, automatic update checks, and — only if you opt in — the cloud AI engines you configure yourself
3. License Activation & Validation
When you activate or revalidate a license, TSNLE contacts lic.slohmaier.com (the licensing service operated by Stefan Lohmaier) and sends:
| Data | Purpose |
|---|---|
| License key (UUID issued at purchase) | Verify the key against LemonSqueezy’s records |
| Device hostname (your computer’s name) | Label the activation in the license dashboard |
Device identifier — a SHA-256 hash derived from hardware properties of your device (Windows: registry MachineGuid + system volume serial; macOS: IOPlatformUUID) | Bind the license to your device and enforce the per-device activation limit |
The device identifier is a one-way cryptographic hash. It cannot be reversed to identify your hardware, user account, or any personal information; it is used solely to count and verify device activations.
Validation requests are sent automatically in the background approximately every 14 days and contain only the license key and the device identifier — not the hostname.
4. What Is Stored on Our Server
For each activation, the licensing service stores:
- The license key
- The customer email address (received from LemonSqueezy)
- The device identifier hash
- The device hostname
- Timestamps of activations and validations
- Your IP address at the time of each request (standard web server logging)
No personal information beyond your computer’s hostname is collected. The licensing server is hosted by 1blu AG in Germany.
5. Legal Basis (GDPR)
- Art. 6 (1) (b) GDPR (performance of a contract): processing the license key and the device binding (hostname + device identifier) is necessary to provide the licensed software you purchased.
- Art. 6 (1) (f) GDPR (legitimate interest): processing the IP address and the device fingerprint serves our legitimate interest in enforcing the per-device activation limit and preventing license abuse.
No separate consent is required for this processing.
6. Trial / Evaluation Period
The evaluation period is fully local and contacts no server. During the trial, TSNLE makes no licensing requests whatsoever. The licensing service only ever sees a paid activation — never an evaluation user.
7. Payments
Payments are processed entirely by LemonSqueezy, acting as Merchant of Record and as a separate, independent data controller. LemonSqueezy is US-based, so your payment data is processed in the United States. Stefan Lohmaier does not receive or store your payment details — only the license key and the order metadata required to fulfil the license agreement. See LemonSqueezy’s privacy policy: https://www.lemonsqueezy.com/privacy
8. Automatic Update Checks
TSNLE checks for software updates once daily:
- Windows: via WinSparkle — an HTTPS GET request to
dl.slohmaier.com/appcast/tsnle-win.xml. The request includes the app version and WinSparkle version in the User-Agent header. - macOS: via Sparkle — an HTTPS GET request to
dl.slohmaier.com/appcast/tsnle-mac.xml. The request includes the app version and macOS version in the User-Agent header. System profiling (SUEnableSystemProfiling) is not enabled.
No hardware details, system profile, or personal information are sent with update checks. Downloaded updates are verified against an Ed25519 signature before installation.
9. AI Features (Opt-In)
TSNLE offers AI-assisted features such as speech-to-text transcription and frame descriptions. All AI features are disabled by default and only run after you explicitly enable and configure them.
Local processing: By default, when enabled, AI features use engines that run entirely on your device — whisper.cpp for transcription and Ollama for local language models. With local engines, your audio, video frames, and transcripts never leave your device.
Optional cloud engines: You may optionally configure a cloud AI provider — OpenAI, Groq, Google Gemini, or Anthropic — by entering your own API key. Only if you do so, TSNLE sends the audio segments and/or video frames you are processing directly to the provider you selected, which acts as an independent data controller under its own privacy policy. This happens only after your explicit configuration — never automatically. We do not receive, store, or forward any of this data; the connection goes directly from your device to the provider.
Legal basis: Art. 6 (1) (a) GDPR (consent, given by enabling and configuring a cloud engine). You can withdraw consent at any time by removing the API key or switching back to a local engine. Please review the privacy policy of the provider you configure before enabling it.
10. Local Data Storage
TSNLE stores your preferences, license state, projects, and transcripts locally on your device only:
- Windows: Preferences and license state are stored in the Windows Registry at
HKEY_CURRENT_USER\Software\TSNLE. To delete, uninstall via Windows Settings and removeHKEY_CURRENT_USER\Software\TSNLE. - macOS: Preferences and license state are stored in
~/Library/Preferences/(UserDefaults) and are not synced to iCloud. To delete, uninstall the app and rundefaults delete com.slohmaier.TSNLEin Terminal.
Project files, media, and transcripts live wherever you save them and are never uploaded by TSNLE.
11. Retention & Your Rights
Your activation data is retained for as long as the license and the activation exist. Deactivating a device in the app immediately deletes that device’s activation record from the server.
Under the GDPR you have the right to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and to object (Art. 21) to the processing of the data held about you on the licensing server. You can also view and reset your own activations at any time via the self-service portal at https://lic.slohmaier.com/portal.
No automated decision-making or profiling within the meaning of Art. 22 GDPR takes place.
You also have the right to lodge a complaint with a supervisory authority. The authority responsible for us is the Bayerisches Landesamt für Datenschutzaufsicht (BayLDA), Promenade 18, 91522 Ansbach, Germany (www.lda.bayern.de).
To exercise your rights, email support@slohmaier.com with the subject “Privacy Request — TSNLE”. Requests are handled within 30 days.
