Data Deletion Policy. Transparent control over your information.

Governed by Cibru Interactive (cibru.in) • Lead Developer: Krishna Moni Borah • Release: v0.1.0

Commitment to Data Minimization & User Autonomy

At Cibru, our primary architectural principle is local-first processing. We do not maintain centralized user databases, social graphs, or persistent logs of your private activity. Below are instructions for managing, un-linking, and permanently deleting data associated with WorldCal Multi-Calendar.

1. On-Device & Transient Data

All preferences, cached media, local history, and application settings for WorldCal Multi-Calendar are stored exclusively on your device using encrypted local storage (EncryptedSharedPreferences).

To instantly clear local on-device data:

1. Open Android Settings → Apps → WorldCal Multi-Calendar.

2. Tap Storage & cache → Clear storage (or uninstall the app).

3. All local configuration, cached tokens, and encryption keys are immediately wiped from your device.

2. Anonymous Referral Rewards Data

If you participated in the optional Free Premium Referral program, an anonymous referral profile was generated to tally credited installs and award Pro access.

Turn Off Sync on This Device:

You can immediately disconnect this device from future referral sync and halt milestone checks by visiting our dedicated unsync page:

Open Unsync Management Page
Permanent Profile Deletion:

To permanently erase your anonymous referral profile and credited events from our servers, email us at support@cibru.in with your referral code. Completed deletion purges your profile; a one-way anti-abuse hash is retained for up to 90 days before final cleanup.

3. Purchase Verification Data (Google Play)

Google Play manages all credit card and payment processing directly. Cibru never receives or stores your full payment credentials. Our verification server receives only the package name, product ID, and purchase token to validate subscription status.

In-App Purchase Data Deletion Action:

If you have an active or pending Google Play purchase recognised on your device:

  1. Open WorldCal Multi-Calendar and tap the Pro or Premium status banner.
  2. Under active membership settings, tap Delete purchase verification data.
  3. Confirm the prompt. The app will immediately pause purchase syncing and request verification deletion from our server.
Important: Deleting verification data does not cancel your Google Play subscription. Please cancel your subscription separately in the Google Play Store (Profile → Payments & subscriptions → Subscriptions).

4. Submitting a Direct Deletion Request

You do not need to install the app or purchase a subscription to request data deletion. Pursuant to the DPDP Act 2023, GDPR Article 17, and California Consumer Privacy Act (CCPA/CPRA), you may submit a deletion request at any time.

To request manual deletion, send an email to:

support@cibru.in

Please specify in your request:

  • App Name: WorldCal Multi-Calendar
  • Scope of request: Referral Profile, Purchase Verification, or General Inquiries
  • Referral code or Google Play Order ID (GPA.XXXX-XXXX-XXXX-XXXXX), if applicable

We will verify your request and confirm completion within 30 days. No fee is charged for standard deletion requests.

5. Official Application Deletion Charter

Data Deletion Instructions | WorldCal Multi-Calendar · CIBRU CIBRU · WorldCal Multi-Calendar worldcal.app # Data Deletion Instructions **WorldCal Multi-Calendar** · Android package: `worldcal.app` Effective Date: October 20, 2026 · Operator: CIBRU (support@cibru.in) At CIBRU, we respect your right to control and request deletion of your data. Because WorldCal Multi-Calendar is designed with an offline-first, on-device architecture, calendar workspaces, profiles, bookmarks, notes, and settings normally remain only in the app’s private storage. Referral and purchase-verification features create separate app-scoped server records only when those features are used. ## 1. On-Device Data Deletion To completely delete all locally stored data, cache, and settings on your Android device: - Open Android **Settings** > **Apps** > **WorldCal Multi-Calendar**. - Tap **Storage & cache**. - Tap **Clear storage** (or **Clear data**). *Effect:* This removes the app’s local DataStore, SharedPreferences, bookmark/workspace data, cache, purchase state, referral state, and settings from the device. Uninstalling the app also removes its private app storage, but uninstalling alone does not request deletion of any server-side referral or purchase-verification record. **Clear cache alone is not a full reset.** Clear storage also removes local identifiers and sync-pause settings. After a reset or reinstall, Play purchases may be discovered and verified again; referral synchronization remains off until you open Get Free Premium. Copies you deliberately shared through other apps are outside WorldCal’s local storage. Neither a local reset nor uninstalling cancels a Google Play subscription. ## 2. Referral Profile Deletion (Server-Side) If you participated in the optional Referral Rewards Program, use the **Unsync** link to turn off synchronization and email support to request server deletion. Unsync stops referral jobs, discards late results, and clears local reward, profile-link, registration, and referrer caches. It retains the authentication session and server profile for explicit re-consent or deletion; a separate valid paid subscription is unaffected. If the app cannot save the pause, it reports that only this session is paused and asks you to retry. - Open the Unsync Referral page on the Android device where WorldCal is installed and tap **Turn Off Referral Sync**. The rewards screen’s Unsync link opens the same page. Confirm the app shows **Referral sync turned off**; viewing this web page alone does not change the app. - To request permanent server deletion, email support@cibru.in with your app name and referral code if available. We may request additional information to verify the request. A completed app-scoped deletion removes the referral profile, events involving it, installation records, and request-limit records; other installations’ links to that profile are removed. A one-way device-key marker expires after 90 days and is removed by scheduled cleanup, which may be delayed during an outage. Shared Supabase authentication data and other apps’ records are not deleted by this operation. Confirmed in-app deletion clears the local session; a failed cleanup retains paused retry information. Reopening **Get Free Premium** can enable sync again unless deletion is pending; deleted rewards are not restored merely by reinstalling. ## 3. Google Play Purchase Records If you purchased an in-app subscription and wish to delete your purchase verification records, please see our dedicated Purchase Data Deletion Guide. Note that deleting purchase data does not cancel active billing; subscriptions must be canceled in the Google Play Subscription Center. ## 4. Contact Us **Third-party records:** Clearing WorldCal storage does not remove Google Play order history, AdMob records from earlier ad interactions, or provider-managed logs/backups. This version blocks production ad requests; its debug test-ad SDK still has Google’s data practices. Use Google account/Android ad-privacy controls or contact the relevant provider for those records. Supabase app-scoped deletion covers the records described above, not every service-level authentication or operational record. If you have any questions about data deletion or need assistance, contact CIBRU support. Include the app name and your referral code or Google Play GPA order number if available; never send passwords, card details, or raw purchase tokens.
