Privacy Policy

1. Information processed on your device

Saved calculations, stock names, and your theme and language settings are stored only on your device. They are never sent to the Operator's servers, and the Operator cannot see them. Deleting the app deletes them — there is no separate backup.

2. Advertising and privacy choices

Google AdMob may process the advertising ID and other device identifiers, approximate location inferred from IP addresses, app launches, ad views and clicks, and error and performance diagnostics to provide and measure ads and prevent fraud. Calculation inputs and document contents are not included in ad requests. Loading ads in advance can involve network communication before an ad appears.

Where consent is required, Google’s consent management tool presents choices. When the advertising privacy options entry appears in Settings, you can review or change those choices. You can also reset or delete the advertising ID in Android settings. Deleting that ID or rejecting personalised ads does not stop all advertising-related processing.

Retention, deletion and international processing by Google are described in the Google Privacy Policy and Google’s partner services information. Once an ad-removal purchase is verified, the app stops new ad requests; information already processed is not automatically deleted.

3. Purchase information

Remove ads is a one-time Google Play in-app purchase, not a subscription. The app processes Google Play purchase information to verify and restore ownership and stores the purchase status on the device. Payment details such as card numbers are not provided to the Operator, and the app does not send purchase information to the Operator’s servers.

4. Storage, deletion and requests

Internal app data stays on your device to provide the features. Clearing app data or uninstalling the app removes internal data, which the Operator cannot restore. Copies you save, export or share separately must be deleted at their storage location or from the receiving service.

If you email the Operator, the Operator processes your email address and message to reply. Do not send unnecessary documents, passwords or payment details. For access, correction, deletion, restriction of processing or withdrawal of consent, contact twinkle.ai.labs@gmail.com. For on-device data the Operator does not hold or information managed by Google, the Operator explains how to act through the relevant device or service.

Inquiry information is deleted without undue delay after the response and follow-up are complete, unless retention is required by law, in which case it is kept for the legally required period.

5. Children and contact

The Service is not directed at children under 16. If you believe a child’s personal information has been provided to the Operator, contact twinkle.ai.labs@gmail.com. The Operator is Twinkle AI Labs, a name used by an individual.

6. Changes

Revisions and their effective dates are announced on Polaris and in the app policy screens: at least 7 days before ordinary changes and 30 days before material or unfavourable changes.
