Privacy Policy for Aurum Periodic Tabel
Last updated: October 22, 2026
1. About this policy
Aurum Periodic Tabel (the “App”) is an Android educational application published by L.E.T. Apps Studio (“we”, “us”, or “our”). It provides periodic table information, element details, reference material, chemistry calculators, quizzes and interactive scientific simulations.
This Privacy Policy explains how information is handled when you use the App. It applies specifically to Aurum Periodic Tabel, not to other apps published by the same developer.
The App’s core educational features run on your device and do not require an App account. We do not sell personal information or use it for targeted advertising.
2. Information stored on your device
The App stores information locally to remember your choices and support its features. This includes language, theme, text size, sound, haptic and motion preferences; favourite and recently viewed elements; calculator inputs and settings; quiz and study progress, custom practice selections and practice results; and simulation credit balances, spending records, refill dates and subscription or test-purchase state.
Credit records can include randomly generated session identifiers, transaction references, timestamps and a saved time-zone reference. They help prevent duplicate deductions or duplicate credit grants.
The current test build does not upload your element browsing history, calculator inputs, practice results or local study records to a developer-operated server. We do not provide a cloud study-history library or automatic cross-device study-data synchronisation.
3. Simulation credits and subscriptions
The App uses one shared credit balance across its simulations. It includes a free monthly allowance and Basic, Pro and Unlimited subscription options.
The current test build uses local, simulated subscriptions clearly marked TEST / no charge. These actions do not collect payment-card details, charge money or connect to a live developer purchase-verification service.
If you use a release that offers real Google Play subscriptions, Google Play processes the payment using your Google account. We do not receive your full payment-card number, security code or Google account password.
For a live subscription, purchase and entitlement verification involves product and order identifiers, purchase tokens or receipts, subscription status and expiry, and a randomly generated App installation identifier. Purchase-verification requests also use security identifiers and authenticated session information to check that a transaction is valid and belongs to the correct installation or user session. Network services necessarily receive connection information such as an IP address.
These records are used to deliver and restore purchased access, maintain credits, prevent duplicate grants or fraud, and respond to billing problems. Live billing and its verification backend are not enabled in the current test build. This policy will be reviewed against the actual providers, data flows and retention arrangements before live billing is released.
Uninstalling the App or clearing its data does not cancel a real Google Play subscription. Manage or cancel it in Google Play’s subscription settings.
4. Advertising and analytics
The App contains no advertisements, advertising SDK, rewarded advertisements or option to watch an advertisement for credits. We do not use advertising identifiers for ad targeting.
The current build does not enable a developer-operated behavioural analytics service or upload your study activity for advertising or profiling. Locally recorded practice and credit activity is used for the App’s functionality, not advertising.
5. Unity, Google Play and other service providers
The App is built with Unity and includes Unity In-App Purchasing for its subscription integration. In a release with live purchasing enabled, Google Play and Unity purchasing services can process transaction and technical information needed to operate purchases. Depending on the activated service, this includes installation or player identifiers, device information, session identifiers and country information. This does not mean the App includes Unity Ads.
Google also handles App distribution, updates and platform services under its own policies. Device-level diagnostics or backup services you enable are managed by the relevant platform provider.

Unity Game Player and App User Privacy Policy: https://unity.com/legal/game-player-and-app-user-privacy-policy
Unity IAP privacy information: https://docs.unity.com/en-us/iap/privacy-and-consent/overview
We do not give these providers your local study records to use for targeted advertising. Processing performed independently by a platform provider is described in that provider’s policy.
6. External reference links
The App includes links to scientific sources and reference websites, including Wikipedia, PubChem and other attributed sources. A website is opened when you choose its link.
The receiving website and your browser can process your IP address, browser or device information, cookies and the page requested under their own policies. The App does not automatically send your full study history, favourites or quiz records with a source link.
If this policy is hosted on Google Sites, visiting the policy webpage is also subject to Google’s website and cookie practices. That website activity is separate from local educational activity inside the App.
7. Copying and exporting practice results
When you choose “Copy results as CSV”, the App places the selected practice-results text on the Android clipboard. This can include dates, practice mode, scores, question counts, selected-element counts and time spent.
You decide whether to paste that information into another application or save or share it. Clipboard handling is subject to Android’s protections. Once you send or paste information into another app or service, its privacy practices apply.
Files or copies you save outside the App may remain after you clear App storage or uninstall it.
8. Permissions and device access
Core educational features do not require access to your contacts, camera, microphone, live location or photo library. The App does not read your private messages or request your payment-card details.
The App uses its private Android storage for settings and study data. Internet and billing capabilities support connected purchasing where enabled; external web links are handled through your browser. Core reference, calculator and study features do not require an internet connection.
You can review the App’s permissions in Android settings.
9. Information you send to support
If you email us, we receive your email address, your message and any attachments or diagnostic information you choose to provide. We use this information to respond, troubleshoot problems and handle privacy or purchase enquiries.
Please do not send passwords, full payment-card details or other information that is unnecessary for your request. We do not automatically receive your local study database when you contact support.
10. Sharing and international processing
We do not sell or rent your personal information. Information involved in an optional support request or enabled purchasing service is handled by the email, platform, payment or technical service providers needed to deliver that service.
We may disclose information where required by applicable law or where necessary to investigate fraud, protect users or establish or defend legal rights.
Google, Unity and email providers can process information in countries outside your country of residence. Their policies describe their processing locations and applicable transfer safeguards. The current test build has no deployed developer-operated billing backend.
11. Retention and deletion
Local App information remains until you remove it, clear the App’s storage or uninstall the App. Android backup or device-transfer services may retain or restore copies according to your device settings and the platform provider’s policies. Copies you deliberately export or share must be removed separately.
You can remove local App information through Android Settings > Apps > Aurum Periodic Tabel > Storage > Clear storage, or the equivalent steps on your device. This resets local preferences, study history and local credit records. It does not cancel a Google Play subscription or delete records held independently by Google.
We retain support correspondence only for as long as needed to handle the enquiry, related disputes, security or applicable legal obligations. You can request deletion using the contact details below.
The current test build has no developer-held cloud study database or live purchase database to delete. If live billing is introduced, its retention and deletion arrangements will be disclosed before release. Google and Unity retain records they process under their own applicable policies and obligations.
12. Security
The App uses Android’s application storage protections for local information. Connected purchase verification, where enabled, uses HTTPS and validates purchase authorisation before granting paid access.
No device, transmission or storage method is completely secure. Protect your device and be careful when copying, exporting or emailing information.
13. Your privacy choices and rights
You can use core educational features without creating an App account, choose whether to open external links, decide whether to copy or share practice results, manage device permissions and backups, clear local data, uninstall the App and contact us about information you have sent us.
Depending on where you live and the processing involved, you may have rights to access, correct, delete or obtain a copy of personal information, restrict or object to processing, or withdraw consent where processing relies on consent. You may also complain to your relevant data-protection authority.
Where applicable, we process support information to answer your request and maintain support and security, purchase information to provide a requested paid service, and legally required records to meet our obligations. If a feature requires consent, it must obtain that consent before the relevant processing.
We cannot retrieve or remotely delete information stored only on your device. We can help you identify the relevant local deletion steps.
14. Children and educational use
The App provides educational reference and study features. It does not provide public profiles, user-to-user messaging or a service for uploading children’s study records to developer-operated servers.
A parent or guardian should supervise purchases by a child and use the platform’s purchase-approval settings. If you believe a child has sent us personal information, contact us so we can review the request and remove information where required.
Any release directed at children must have its audience, purchasing services and data-handling configuration reviewed before publication. This policy does not override protections provided by applicable children’s privacy law.
15. Changes to this policy
We will update this policy when the App’s information practices change, including before enabling live subscription verification or introducing a new data-collecting service. The date at the top identifies the latest revision. Where required, we will provide additional notice or request consent.
