Privacy policy

Google AdMob automatic data collection

When ads are permitted, Google AdMob automatically collects or processes these data categories:

• Approximate Location. AdMob derives an approximate location from your IP address.
• App Interactions. AdMob processes advertising interactions, such as ad views and taps.
• Diagnostics. AdMob processes diagnostic data to deliver and measure ads and prevent fraud.
• Device Advertising IDs. AdMob processes device and advertising identifiers for its advertising services.

Personalised ads depend on applicable consent. The app does not request ads before an age choice or for players under 16.

Who makes Cryptic

Cryptic (formerly Cryptoku) is developed by Bipin Rimal, Kathmandu, Nepal. Contact: bipinrimal314@gmail.com. No account or login is required.

Local data

Saved puzzles, lesson progress, solve statistics, age group and preferences are stored locally. An optional profile photo stays in app storage. Imported puzzle links and JSON are decoded locally without fetching the linked page. Android cloud backup is disabled for this release; device migration behaviour may vary by device. Use Settings → Delete local data to erase app progress and the selected photo.

Age privacy

Cryptic is intended for ages 13+. We ask for an age group, not a birthday, and save it locally. Before an age choice, and for players under 16, the app does not request ads or allow its feedback form to send data. Local puzzles remain available. This is not a parental consent service.

Advertising

For players aged 16 or older, Google AdMob provides occasional interstitial ads between puzzles and optional rewarded ads for extra answers, filling notes or opening past daily puzzles. Rewarded ads can be chosen during a puzzle. Before requesting ads, Google’s consent flow checks whether ads may be requested. Where required, change consent under Settings → Ad Privacy Choices. AdMob may process device/advertising identifiers, approximate location from IP, ad interactions and diagnostic data to deliver and measure ads and prevent fraud. Personalised ads depend on applicable consent. Google controls its own retention and privacy processes.

Feedback

Nothing is sent until you press Send. Your message, optional email, app version, operating system version and screen context are sent through FormSubmit to the developer’s email. They are used for support, not marketing. Messages are kept while needed to address the request and related follow-up; records may be retained where needed for legal obligations. Avoid including sensitive information. Request deletion by emailing the developer; this covers records under our control. Provider records are subject to that provider’s retention rules.

Purchases

New memberships and remove-ads purchases are disabled in this Android release. Existing purchases may be checked through Google Play to preserve prior entitlements. We do not receive card or bank details.

Browser storage and cookies

The web app uses localStorage for necessary game progress and preferences, with no advertising or optional analytics in the web code. The native app uses local database/files and the advertising SDK’s storage where ads are allowed. External websites, Google and FormSubmit have their own policies.

Your choices and requests

Use Delete local data for information on this device. Use Request data deletion for feedback or other information sent to the developer; no account is needed. We may ask for enough information to identify the records and verify the request. Where applicable, you can also request access or correction or contact your privacy regulator. Device advertising-ID controls and Google’s privacy tools manage data held by Google. We do not sell personal data.

Changes
