Privacy Policy - CoreVecta Calculator Bundle
The Apps collect nothing. They run entirely on your device - no accounts, no analytics, no advertising, no trackers, no crash reporting, and no telemetry. We have no server that receives your data because the Apps do not send any.
1. What we do NOT collect
We do not collect, and the Apps do not transmit, any of the following:
- Personal identifiers (name, email, phone, device ID, advertising ID).
- Location data.
- Your calculations, inputs, history, unit selections, or saved boards.
- Usage or diagnostics / analytics data.
- Contacts, photos, files, or any device content.
All app state (locale preference, calculation history, currency-board selections, and any license token you activate) is stored only in local device storage and never leaves the device.
2. Network behaviour
Six of the seven Apps (FinanceVecta, ElectronicsVecta, ConstructionVecta, ScientificVecta, ManufacturingVecta, ProgrammerVecta) make no network requests of any kind. Their reference data (e.g. tax tables, component data) ships inside the app as a cryptographically signed pack - nothing is fetched.
ConvertVecta - optional feature (not yet shipped): a future version may offer an optional, user-initiated action to refresh currency exchange rates by downloading a signed, dated FX snapshot. As of this policy's effective date this feature is not present and ConvertVecta makes no network requests. If and when it ships, it will run only when you explicitly tap "Update rates," download a public, non-personalised snapshot that sends no identifiers or usage data, and verify it (Ed25519) before use. This policy will be updated before the feature is enabled.
3. Purchases
The Apps are usable for free. An optional one-time "Pro" upgrade may be offered. We do not process or store your payment details:
- Android (Google Play Billing): Google processes the purchase and handles all payment data under Google's Privacy Policy. We receive only a purchase confirmation sufficient to grant your entitlement.
- Web / browser extension (Merchant of Record - Lemon Squeezy): the Merchant of Record processes checkout and payment under its own privacy policy as the seller of record.
When you redeem a purchase, our stateless license service issues a signed offline license token that contains only an order/subscription identifier - no name, email, or device data. We maintain no user database and store no personal information about buyers.
4. Children
The Apps are general-purpose utilities and are not directed at children. Because we collect no data, we collect no data from children.
5. Data sharing and sale
We do not share, sell, rent, or disclose personal data, because we do not collect any. The payment processors named above handle payment data under their own policies.
6. Your rights
Because we hold no personal data about you, there is nothing for us to access, export, correct, or delete on our side. App data on your device is removed when you uninstall the app or clear its storage. For purchase records held by Google or the Merchant of Record, contact them directly.
7. On this website
No analytics, no cookies, no fingerprinting, no third-party scripts. Static pages served from a CDN. Standard CDN access logs operated by our hosting provider are the only traffic record; we add nothing to them.
8. Changes
We may update this policy (for example, when the ConvertVecta FX feature or purchases ship). The effective date will change and material changes will be reflected in the app listing.
