Privacy Policy
Last updated: October 20, 2026
COGO Survey Calculator is built to be private by design. It works entirely on your device, with no account and no server. We do not collect, track, sell, or transmit your personal information or your survey data.
Who this policy covers
This policy applies to the COGO Survey Calculator apps for iOS and Android (each, the “App”; on Google Play it is listed as “COGO: Land Survey Calculator”), published by Vendrato (“we,” “us”). It also covers this website, cogo.vendrato.com.
Information the App collects
None. The App does not collect personal data. Specifically:
- Your survey data — jobs, points, coordinates, bearings, distances, traverses, and computed results — is stored locally on your device only. It is never uploaded to us or anyone else.
- No account. You don't create an account, sign in, or give us your name, email, or phone number to use the App.
- No tracking. The App contains no advertising identifiers, no analytics or attribution SDKs, and no third-party trackers. We do not build a profile of you or track you across apps or websites.
- No location collection. The App does not request or record your device location.
Data stored on your device
The jobs and points you create are saved locally in an on-device database (Apple's on iOS, the app's private storage on Android) so your work persists between sessions. The App also stores a few small settings (for example, whether you've completed the welcome tutorial and whether you've unlocked Pro) using the system's standard preferences storage. This information stays on your device. If you use iCloud backups on iOS or Android device backup, your survey work is included in your own Apple or Google backup under their control — it is never sent to us. On Android the cached Pro status is left out of backups; Google Play re-confirms it on the new device.
Purchases
COGO Pro is offered as a weekly, monthly, or yearly subscription or a one-time lifetime purchase. On iOS it is sold through Apple's In-App Purchase system (StoreKit); on Android, through Google Play Billing. Apple or Google processes the transaction and your payment information; we never see or receive your payment details. Whether you own Pro is determined on your device from your App Store or Google Play purchase history. We may see anonymized, aggregated sales and subscription statistics in App Store Connect or the Google Play Console, which do not identify you. Your purchase is governed by Apple's Privacy Policy or Google's Privacy Policy.
On-device assistant
On iOS, the optional “Theo” assistant uses Apple's on-device foundation models (Apple Intelligence) where available; the Android app has no assistant. Your questions and your job data are processed on your device; they are not sent to us or to any third party by the App. Availability depends on your device and iOS settings, and the App works fully without it.
Network use
The App is designed to operate fully offline and does not connect to any server operated by us. It will function with no network connection at all. The Android app does not request the internet permission; purchases and restores go through the Google Play Store app.
Children's privacy
The App is a professional tool and is not directed to children. Because the App collects no personal information from anyone, it collects none from children.
Your rights
Because we do not collect or hold your personal data, there is nothing for us to access, correct, export, or delete on our side. You can remove all of the App's data at any time by deleting a job within the App or by deleting the App from your device.
Changes to this policy
If we change this policy, we'll update the date above and post the revised version on this page. Material changes will be reflected here before they take effect.
