1. Data and accounts
No app account is required. The app does not automatically upload casting content, history, or notes to the developer's servers. This version displays no ads and performs no advertising tracking.
We process necessary information only to provide the app functions you acquired or purchased, respond to requests you initiate, and meet legal obligations. Where optional processing requires consent, we explain its purpose and obtain consent. Declining optional location does not prevent standard-time casting.
2. History and notes
Casting results, history, and optional notes you enter are stored on your device. The app does not automatically read or record your question. You can delete records in the app; uninstalling the app normally removes local history and notes. Notes are not written to diagnostic logs, and history does not contain raw latitude or longitude.
Saving a True Solar Time result also saves the corrected time and correction in minutes. Together with the date, these time values may indirectly indicate longitude. They also remain on the device and can be deleted with the history record.
Avoid entering unnecessary information such as your or someone else's identity document numbers or account passwords in notes. Management of your device and its backups also depends on your system settings.
3. Optional location and True Solar Time
True Solar Time is off by default. Only when you enable it does the app request When In Use location permission and briefly use your current longitude and accuracy information for that time correction. Location updates stop once a usable location is obtained or the request times out. The app does not continuously track you.
Raw location is used only on the device for correction. It is not uploaded or written to history or diagnostic logs; time values saved with results are explained in section 2. You may choose approximate location; lower accuracy may affect the correction. You can turn off True Solar Time or revoke location permission in system settings. Standard-time casting and history remain available without location permission.
4. Purchases and access
Apple handles downloads, purchases, and purchase restoration. The app reads Apple-verified acquisition and purchase records to confirm access, and stores necessary purchase status and trial credits on the device. Reinstallation does not grant another set of credits from an earlier free period.
Paid downloads and permanent unlocks provide unlimited casting. People who acquired the app during an earlier free period and have not unlocked it retain their existing trial balance and purchase option. We do not receive your Apple Account password or bank card details. Apple processes information needed for its services under its own privacy policy.
5. On-device diagnostic logs
To troubleshoot startup, access verification, and network issues, the app keeps limited technical logs on your device. These include timestamps, app and operating system versions, relevant operation status, error information, and a random marker distinguishing the current app session.
Logs do not contain casting content, history, notes, location, Apple Account passwords, complete receipts, or complete purchase credentials. They use limited storage, with older records gradually overwritten as files rotate, and are not automatically uploaded. A recipient receives a copy only if you choose to export and share it. Check the recipient before sharing and manage exported files carefully.
6. Contacting support
If you email us or share troubleshooting materials, we receive the email address, issue description, and attachments you provide. We use them only to respond, troubleshoot, and handle necessary security matters. We retain them for the shortest period needed to handle your request, then delete or de-identify information that is no longer needed, except where retention is required by law or necessary to resolve a dispute.
Do not send passwords, bank card details, complete purchase credentials, or personal information unrelated to your request. You can contact us about privacy using the email address below.
7. Minors and children under 14
We recommend that minors use the app with guidance from a parent or other guardian. The app does not require a child's name, date of birth, school, or identity documents.
For a child under 14, a parent or other guardian should read this policy and this section, and consent to and guide the child's use. Guardian consent should be obtained before enabling optional location or sending information to us. A child's history and notes also remain on the device and are not automatically sent to us.
A guardian can turn off location, revoke permissions, or delete records on the device. For information already sent to us voluntarily, a guardian can contact us to request access, correction, or deletion. We will verify requests without collecting excessive information. If we discover that we received a child's personal information without guardian consent, we will stop the relevant processing and delete it promptly, unless retention is required by law.
8. Security and incident response
We protect information through data minimization, restricted access, and on-device safeguards. If we discover an actual or possible disclosure, alteration, or loss of information, we will investigate promptly and take remedial action. We will report to the relevant authorities as required by law and, where legally required, notify affected users or guardians of potential impacts, action taken, and how to obtain help.
9. Your choices and rights
You can turn off optional location and delete history and notes in the app. You can contact us to request access, a copy, correction, deletion, or withdrawal of relevant consent for information we hold because of a support request. We will investigate, handle, and respond within 15 working days of receiving your request. If the law prevents us from fulfilling a request, we will explain why. We cannot retrieve records stored only on your device from a server.
If you disagree with the outcome, you can contact us again using the privacy email address, complain to the relevant authorities, or seek a legal remedy.
Core casting and history work offline. Purchases, synchronization with Apple, and opening the website, support, or privacy pages may require a network connection.
10. Storage locations and retention
| Information | Storage and retention |
|---|---|
| History, notes, and time values saved with results | Stored on your device, with up to 100 history records. You can delete records; older records may also be removed when the limit is reached |
| Raw location for the current correction | Used only while the app runs, without persistent storage. Turning off the feature clears the relevant location state |
| On-device diagnostics | Older records are overwritten as limited-capacity files rotate. A voluntary export includes at most the available records from the preceding seven days |
| Purchase status and existing trial credits | Kept on the device as needed to provide access and prevent repeat credit grants; these may remain after reinstallation |
| Support materials you send | Held in the support channel that receives them, for the shortest period needed to handle the request. Unneeded information is removed; necessary legal or dispute-related retention is limited to its purpose |
We do not operate a developer cloud database containing your local history, notes, or raw location. These on-device descriptions do not replace the storage rules of Apple or email and backup services you choose.
11. Third-party services and information disclosure
| Service | When it is used and relevant information | More information |
|---|---|---|
| Apple App Store, purchase, and restoration services | Apple processes relevant account and transaction information for downloads, purchases, access verification, and restoration; the app reads necessary verified status | App Store and privacy |
| iOS Location Services | Provides longitude and accuracy for the current correction only after you enable True Solar Time and grant permission. System services also process information according to your system settings | Location Services and privacy |
| System sharing, email, and other services you choose | Sends the materials you choose to your selected recipient only when you voluntarily export, share, or contact support | Check the privacy rules of your selected service and recipient |
We do not sell personal information or use support materials for advertising. If information must be provided to an authority by law, we limit processing to the legally required scope. A policy update does not itself expand optional permissions or change choices you have already made.
12. Policy updates and contact
If the scope of processing changes materially, we will provide notice and obtain consent where required by law.
