Decode & Deduce: Cryptogram is a single-player letter-puzzle and deduction game. Playing does not require an account or submitting feedback.
Data handled by the game
The game stores puzzle progress, case completion records, case play time and language preference on your device. These records are processed locally and are not automatically uploaded to us. The game does not include advertising, third-party gameplay analytics or cross-app tracking.
Planned purchases in version 1.1
Version 1.0 has no in-app purchases. Version 1.1 (not yet released) will add optional purchases through Apple's in-app purchase system. To verify access to Case Pack 1 and restore purchases, the app will use verified purchase information supplied by StoreKit. It will store a local entitlement record containing the product identifier, original transaction identifier, purchase date, any revocation date, and purchase environment. StoreKit's verified transaction history and updates will be used to keep access current. Tapping Restore Purchases will ask StoreKit to synchronize purchases. Restoring purchases will restore access to the pack, not local puzzle progress.
Information you choose to send
If you submit the Tally feedback form, we receive your description and any category, place in the app, screenshot or reply email address you choose to provide, together with the form’s submission records. Tally hosts and processes responses on our behalf. We use them to understand feedback, investigate problems, improve the app and respond if you provide an address. We do not post feedback publicly. When you submit feedback, Tally generates a submission ID and a random respondent ID. If you provide a reply email address, it is stored with that feedback. Unsubmitted answers may be stored temporarily in your browser on your device so you can continue later.
If you email sukilu07@foxmail.com, we receive your email address, message and attachments. Our email provider processes that correspondence so we can handle your request. Forms and support emails are optional and are not conditions for playing. We do not sell feedback or use it for advertising or cross-app tracking.
External webpages and service providers
Support and privacy pages are hosted by Google Sites; feedback forms are hosted by Tally. Opening them sends ordinary connection information, such as an IP address and browser information, to these providers. They may process technical information for hosting, security and operating their services. This is separate from local game records; the app does not automatically send those game records to Google Sites or Tally. Tally also provides anonymous, aggregated statistics for the feedback webpage, including visits and submissions, time spent, traffic sources, device category, browser, operating system, and approximate country or city. These statistics do not include game progress. Tally states that its visit analytics do not use cookies or cross-device tracking.
Provider information: Google Privacy Policy; Tally Privacy Notice; Tally form-response processing.
Retention, deletion and your choices
We keep feedback and support correspondence only as long as needed to investigate it, handle the request and complete related follow-up, unless law requires longer retention. Contact sukilu07@foxmail.com to request access, correction or deletion of information we hold about your feedback.
For a submission without an email address, provide its approximate submission time and enough context to help us locate it. We may be unable to identify it if the information is insufficient. Deletion from our working records may not immediately remove provider backups. Tally describes response deletion and backup handling in its service documentation. We handle requests for records we control using available provider deletion controls.
Version 1.0 lets you change the game language in Settings. Version 1.1 (not yet released) will use English without a language-selection control; it will still keep a local language-preference value, normalized to English. Deleting the app removes local app data from the device; backups, if enabled, are managed through your device and Apple settings. We cannot access or erase your local progress remotely.
We will update this policy if our practices change.
