What we collect and how to opt out
Purpose
tsuku collects anonymous telemetry to help us understand which tools are most used and which platforms need support. This data helps us prioritize recipe development and make informed decisions about platform compatibility.
What We Collect
When you install or update a tool, tsuku sends a single telemetry event containing:
| Field | Example | Purpose |
|---|---|---|
recipe |
nodejs | Know which recipes are used |
version |
22.0.0 | Track version adoption |
os |
linux | Platform support decisions |
arch |
amd64 | Architecture support |
tsuku_version |
0.3.0 | Track tsuku adoption |
action |
install | Distinguish installs from updates |
When an auto-update succeeds, fails, or triggers a rollback, tsuku sends an outcome event containing:
| Field | Example | Purpose |
|---|---|---|
action |
update_outcome_success | Track update reliability |
recipe |
nodejs | Identify which tools fail |
trigger |
auto | Distinguish auto from manual updates |
error_type |
download_failed | Categorize failures (fixed taxonomy, never raw error text) |
os, arch, tsuku_version |
linux, amd64, 0.5.0 | Same as above |
Error classification uses a fixed set of categories (like download_failed or
checksum_failed). Raw error messages, which may contain file paths, are never transmitted.
What We Do NOT Collect
We are committed to your privacy. tsuku does not collect:
- IP addresses
- User identifiers or account information
- Hostnames or machine names
- File paths or directory structures
- Environment variables
- Any personally identifiable information (PII)
How to Opt Out
You can disable telemetry at any time by setting an environment variable:
export TSUKU_NO_TELEMETRY=1
Or, disable telemetry during initial installation:
curl -fsSL https://get.tsuku.dev/now | bash -s -- --no-telemetry
When telemetry is disabled, tsuku will not send any data. The tool works identically whether telemetry is enabled or disabled.
Data Retention
- Raw events: 90 days
- Aggregated statistics: Indefinitely
Aggregated statistics contain no individual event data and cannot be traced back to any specific installation or user.
Source Code
Both the telemetry client and backend are open source:
