Privacy Policy
1. Who we are
DixSystem is the developer and publisher of DIX, an AI-powered Linux kernel optimization application. For the purposes of GDPR, DixSystem (Spain) is the data controller. You can reach us at privacy@dixsystem.com.
2. What data DIX collects
When you run an analysis, DIX reads the following kernel and hardware parameters from your local system and sends them to the analysis backend:
- CPU governor (e.g.,
performance,powersave) - I/O scheduler (e.g.,
mq-deadline,kyber) - RAM size (in GB)
- Linux distribution and kernel version
- Selected sysctl values (swappiness, dirty_ratio, hugepage mode, NUMA balancing state)
- GPU power state (discrete/integrated — model name only)
These parameters are technical and designed to avoid personal data. They are limited to the whitelist below.
3. What DIX does NOT collect
The exact whitelist of parameters that may be sent is enforced in the application source code at src-tauri/src/policy.rs.
4. Where your data goes
The kernel parameter snapshot is sent to the Anthropic Claude API solely to generate your optimization recommendations. Anthropic processes this data as a sub-processor under their API terms of service. No data is stored on DixSystem servers beyond what is strictly necessary to return the analysis result.
Anthropic's privacy policy is available at anthropic.com/privacy.
5. DIX Atlas (roadmap / opt-in telemetry)
DIX Atlas is a planned optional feature. When released, it will require explicit opt-in and is intended to contribute minimized hardware-performance pairs to a collective dataset used to improve future recommendations.
- Opt-in only. It will be disabled by default. You must actively enable it.
- Planned shared fields: a salted one-way hardware hash, the kernel profile applied, and a performance delta where available. Re-identification risk will be reviewed before rollout.
- What is never shared intentionally: your license key, name, email, IP, or any system identifier in plain form.
- Withdrawal: once Atlas is available, you will be able to disable it from the application settings. Disabling it will stop future submissions.
6. Legal basis (GDPR)
Processing of kernel parameters for analysis purposes is carried out on the legal basis of contract performance (Article 6(1)(b) GDPR) — it is necessary to deliver the service you purchased. Atlas telemetry, when available and enabled, will be processed on the basis of consent (Article 6(1)(a) GDPR).
7. Data retention
Analysis requests are not stored beyond the time required to generate and return the response. License validation records are retained for the duration of the license. Atlas retention rules will be published before the feature is released.
8. Your rights
Under GDPR you have the right to access, rectify, or erase personal data we hold about you, and to object to or restrict processing. To exercise any of these rights, contact privacy@dixsystem.com. We will respond within 30 days.
9. Changes to this policy
We may update this policy as the application evolves. Material changes will be communicated via the application or the website. Continued use after the effective date constitutes acceptance.
