DocDiet privacy policy
Effective date: 2026-09-30 · Applies to the DocDiet desktop app (Windows / macOS / Linux) · Developer: Indmaksoft · https://www.indmak.com
1. What we do NOT collect
- ❌ Document contents — your .docx/.xlsx/.pptx files are read and written locally only, never uploaded.
- ❌ Accounts — no registration, no sign-in, no email binding.
- ❌ Analytics / ads / crash reports — the client integrates no analytics, advertising, or telemetry SDKs.
- ❌ Payment details — purchases happen in the browser via the payment provider; the app never touches card data (it only opens the purchase page).
2. What is transmitted online (two cases only)
2.1 Trial & license verification
| Case | Fields sent | Notes |
|---|---|---|
| Start / check trial | Device fingerprint, device name, product id docdiet |
Fingerprint is sha256:<hex> derived from the OS machine id — the raw machine id is
never transmitted; device name is the system computer name (unknown-device if unavailable),
used only for display and abuse prevention. |
| Activate / verify / deactivate license | License key, device fingerprint, device name | The key travels in the POST body, never in the URL; everything over HTTPS. |
| Release a seat (deactivate) | License key, device fingerprint | Only released after the server confirms; offline, the local license is kept so you are never locked out by mistake. |
2.2 Update checks
Tapping “Check for updates” sends: product id, channel (stable), operating system, CPU architecture. The reply contains only a version number, release notes, download link, hash, and size. Nothing is downloaded or installed silently — you decide in the browser.
3. What lives on your computer
| Location | Contents | Purpose |
|---|---|---|
App data folder com.indmak.docdiet |
license.json (signed offline license), trial.json (trial record),
sync.json (sync cadence, no secrets), seen.json (clock-rollback watermark) |
Offline use + license checks |
| Same folder (some systems only) | device-id |
Random fallback id when the OS provides no machine id |
| App preferences | Compression settings, last 100 compression records (output folder, bytes saved) | Settings memory + History page |
All of the above are local files you can delete at any time (deleting the license/trial files signs you out locally; re-activate or go online to correct). Remove them together with the app on uninstall.
4. Third parties
- Payment provider (Creem) — checkout happens on an external web page governed by its own privacy policy; the DocDiet client never handles payment data.
- No other third-party SDKs — no analytics, push, ads, or crash-reporting components are embedded in the client.
5. Retention & deletion
- Trial/license records are kept to operate the licensing service; deactivating frees the device seat server-side.
- To delete server-side records tied to your device fingerprint, contact us via the Support page and we will process it after verification.
- Local data: delete the files above or uninstall the app.
6. Minors
This is a general-purpose office utility with no child-directed content or marketing; purchase and activation should be performed by a person with full civil capacity.
