Privacy Policy
TariffSwitch by LokiSec
Effective: 2026-06-19 · Publisher: LokiSec · Contact: privacy@lokisec.de
Our commitment
TariffSwitch is built on the principle that your tariff and usage data is your own. This app is local-first, works entirely offline, and we collect zero personal data by default.
What we collect
Nothing. TariffSwitch stores all data locally on your device. There is no account, no cloud backup, and no tracking by default.
We do not collect:
- Your name, email, or contact information
- Your tariff windows, price curves, appliances, or usage schedule
- Location data or device identifiers
- Telemetry, crash reports, or usage analytics (by default)
Data storage
All TariffSwitch data is stored in app-private local storage on your device only. This data:
- Is never sent to LokiSec servers
- Is never shared with third parties
- Remains yours to delete at any time
- Is lost only if you uninstall the app or factory-reset your device
Optional features
Google Drive Sync (Optional)
If you choose to enable Google Drive sync, backups are stored in your own Google Drive account in a private appDataFolder that only this app can access. LokiSec does not operate any sync server and has no access to your synced data. Sync is entirely optional and the app works perfectly without it. You can disable sync at any time and delete your backup from Google Drive.
Local Home Assistant Price-Sensor Read (Optional)
If you choose to configure it, TariffSwitch can perform a read-only poll of a Home Assistant price sensor on your own network. This is off by default; the host and any token are stored in encrypted preferences on your device, and the data never leaves your LAN. TariffSwitch never controls devices and never logs into a provider. LokiSec operates no server and never sees it.
Optional Affiliate Links
TariffSwitch may show clearly-labelled links to schedulable smart plugs and EV chargers in a single settings entry. These links are completely optional, never required to use any feature, and never tracked by LokiSec.
Purchases
Some apps include in-app purchases (an optional support purchase or a one-time unlock). Payments are processed by Google Play; LokiSec receives only a confirmation that a purchase was made and collects no payment details or other personal data.
Permissions explained
| Permission | Why | Required? |
|---|---|---|
INTERNET | Only for an optional, read-only, user-configured poll of a local Home Assistant price sensor | No — manual windows and CSV import work fully without any network access |
Data export and deletion
You always retain full control:
- Export your tariff, price-curve and appliance data as CSV or JSON via Settings → Export
- The file is written to a location you choose (Drive, local storage, email to yourself)
- Delete the app at any time to immediately remove all local data
- If you've enabled Drive sync, delete the backup from your Google Drive separately
Legal compliance
GDPR: We collect no personal data, so there is nothing on our servers to access or delete — your data is yours and lives on your device. TariffSwitch is not marketed to children, and we do not knowingly collect data from anyone under 13.
Security
All local data is stored in app-private storage with standard Android file permissions. If you enable Drive sync, encryption is handled by Google Drive. The app does not store passwords or credentials in plain text.
Changes to this policy
We may update this policy occasionally. The "Effective Date" at the top shows when it was last updated. Continued use of TariffSwitch after changes constitutes acceptance of the updated policy.
