Privacy Policy — Vector Curve
App name: Vector Curve
Package name: com.vectorcurve.app
Effective date: 14 September 2026
This Privacy Policy explains how Vector Curve (“we”, “us”, “our”) handles information when you use the Android app Vector Curve.
Vector Curve is a drawing app for creating vector illustrations and patterns. It is designed to work offline. We do not operate user accounts, and we do not upload your drawings to our servers.
1. Who this policy covers
This policy applies to Vector Curve as distributed through Google Play. It does not apply to websites, apps, or services that we do not control, including Google Play itself.
If you contact us by email, this policy also covers the information you send us in that message.
2. Information we do not collect
We do not:
require an account, login, name, email address, or phone number to use the app
collect your precise or approximate location
access your contacts, calendar, microphone, or camera
show ads
use advertising identifiers
use analytics, crash-reporting, or tracking SDKs of our own
sell, rent, or trade your information
upload your drawings, imported images, or exported files to our servers
3. Information stored on your device
The app stores the following only on your device, in the app’s private storage and Android preferences:
drawings and vector data you create
saved drawings, elements, and pattern-brush stamps, including thumbnails
imported images and SVG content you place on the canvas
brush presets, color palettes, canvas and tool settings, and similar preferences
auto-saved work so you can continue after you leave the app
This information stays on your device unless:
you export a file to a folder you can access (such as Pictures/VectorCurve or Downloads/VectorCurve)
you choose a file in the system picker so the app can import it
your device’s own backup or transfer features copy app data (see section 7)
We cannot see this information. Uninstalling the app deletes the app’s private data from the device, subject to any copies already exported or backed up by your device or operating system.
4. Files you import or export
You may import images or SVG files using the Android system file picker. The app reads only the file you select, and only to place it in your drawing. We do not upload those files.
When you export, the app writes files you requested (for example PNG, SVG, or a layered ZIP) to device storage. Those files are yours. Other apps on your device may be able to access folders such as Pictures or Downloads, depending on your Android version and permissions.
5. Purchases and Google Play
Optional Premium features are sold through Google Play Billing. Available options are:
a monthly auto-renewing subscription (premium_monthly)
a yearly auto-renewing subscription (premium_yearly)
a one-time lifetime purchase (premium_lifetime)
To show prices, complete a purchase, restore a purchase, and confirm whether Premium is active, the app connects to Google Play. That is why the app requests internet access.
Payment details (such as your card or Google payment method), your Google account identity, and Google’s purchase records are processed by Google, not by us. We do not receive your full payment card number, billing address, or Google account email through the app.
Through the Play Billing library, the app receives purchase status needed to unlock Premium on that device and Google account (for example product ID and whether a purchase is active). We do not operate our own payment server, and we do not build a profile of you from purchases.
Google’s handling of purchase data is described in Google’s privacy policy: https://policies.google.com/privacy
6. Permissions
The app requests only:
Permission
Why
Internet
Communicate with Google Play for product prices, purchases, and restoring Premium. Drawing does not require a network connection.
Google Play Billing
Offer and restore in-app purchases and subscriptions.
The app does not request storage, photos, camera, microphone, location, or contacts permissions. Imports use the system picker, which does not require those permissions.
7. Android backup and device transfer
The app allows Android backup (allowBackup). If you have turned on backup or device transfer in Android settings, Google or your device manufacturer may copy app data — including drawings stored in the app — to your own backup account as part of the system backup. We do not receive that backup, and we do not control Google’s backup service.
You can manage backup in your device settings. See also: https://support.google.com/android/answer/2819582
8. Diagnostic logs
The app may write technical logs on the device while it runs (for example, whether an export succeeded). We do not transmit those logs to ourselves. They remain on the device unless you or Android (for example, a bug report you choose to send) share them.
9. How we use information
We use information only to:
provide drawing, saving, import, and export features on your device
unlock Premium after Google Play confirms a valid purchase
reply if you contact us
We do not use your artwork to train models, for advertising, or for any purpose other than running the app on your device.
10. Who we share information with
We do not sell personal information.
The only third party involved in normal use of the app is Google, as the distributor of the app and the processor of Play purchases and, if you enable it, Android backup. We do not share your drawings with Google except to the extent Android’s own backup feature does so under your device settings.
If you email us, we use that message only to respond. We do not add you to a marketing list.
We may disclose information if the law requires it. Because we do not hold your drawings or an account database, we generally have nothing of yours to disclose beyond an email you sent us.
11. Children
Vector Curve is not directed at children under 13 (or the equivalent minimum age in your country). We do not knowingly collect personal information from children. The app does not include accounts, social features, or ads.
Purchases require a Google Play account that is allowed to pay. A child’s purchases should be made only with a parent or guardian’s approval through Google Play family settings.
If you believe a child has sent us personal information, contact us and we will delete it.
12. How long information is kept
On-device artwork and settings: kept until you delete them in the app, clear the app’s storage, or uninstall the app.
Exported files: kept until you delete them from device storage.
Purchase status: held by Google according to Google Play’s policies. The app checks that status when it connects to Google Play; we do not keep a separate purchase database.
Emails you send us: kept only as long as needed to handle your request, unless we must keep them longer for legal reasons.
13. Security
Artwork is stored in the app’s private storage, which other apps cannot normally read. No method of storage is perfectly secure. Protect your device with a screen lock, and be careful about files you export into shared folders.
We do not transmit your drawings, so there is no developer server holding your artwork to breach.
14. Your choices and privacy rights
Depending on where you live, you may have rights to access, correct, delete, or export personal information, or to object to certain processing.
Because we do not hold your drawings or an account profile:
to delete artwork, delete it in the app, clear the app’s storage, or uninstall the app
to stop future purchases, cancel a subscription in Google Play (see the Terms of Use)
to manage Play purchase records, use your Google account settings
if you emailed us and want that email deleted, contact us and we will delete it unless we must keep it by law
We do not “sell” or “share” personal information as those terms are used in the California Consumer Privacy Act. We do not use your data for cross-context behavioral advertising.
Residents of the EEA, UK, and Switzerland: the legal basis for using an email you send us is our legitimate interest in answering you, or steps taken at your request. On-device processing of your artwork is done on your device to provide the app you asked for. You may lodge a complaint with your local data protection authority.
15. International transfers
We do not transfer your drawings to another country because we do not receive them. Google may process Play purchase data in countries where Google operates, under Google’s own terms and privacy policy.
16. Changes to this policy
We may update this policy if the app changes. The new version will show a new effective date. If a change materially affects how we handle personal information, we will provide notice in a reasonable way, such as in the app or on this page. Continued use of the app after the update means you accept the updated policy, to the extent allowed by law.
