The following data is created and kept on your device. We have no access to it, and it is not transmitted to us, to our advertising partners or to any other third party:
You can delete this data at any time in the App, or by uninstalling the App.
The App asks for permissions only when you use a feature that needs them. You can grant or revoke any permission at any time in your device settings. Refusing a permission only disables the related feature.
With your permission, the App reads your device contacts to display birthdays in the Birthdays section, send birthday reminders, attach a contact to an event, and send event invitations. Contact data, including names, birthdays and photos, is processed only on your device. It is never uploaded to our servers, sold, shared with third parties, or used for advertising. Access is requested only when you use a contact-related feature, never at app launch.
With your permission, the App records voice notes that you attach to events. Recordings are stored only on your device and are never uploaded to our servers or shared with third parties.
With your permission, the App reads and writes events in the calendars on your device so that you can see and manage all your events in one place. See section 5 for details.
The App uses notification and exact alarm permissions to deliver reminders for your events and birthdays at the right time.
If you enable app lock, you can unlock the App with your fingerprint or other biometric method. Biometric data is handled entirely by your device's operating system. The App never receives or stores it.
The App does not request access to your device's location.
With your permission, the App shows and edits events from the calendar accounts already added to your device, such as Google, Microsoft Outlook, Exchange, Samsung or other providers. Synchronization of these accounts with their providers is performed by Android or by the provider's own app, not by Calendar MC. The App does not receive your passwords for these accounts and does not send their events to our servers.
If you choose to sync with Google Calendar directly in the App, you sign in with your Google account and the App accesses your calendar events through the Google Calendar API. This data is exchanged directly between your device and Google. It is used solely to display, create and update your events in the App. It is not stored on our servers, not shared with advertising partners, not used for advertising and not sold.
Calendar MC's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
You can revoke the App's access to your Google account at any time at myaccount.google.com/permissions.
We use the following Google services. They process data on our behalf and under their own privacy terms.
| Service | Data | Purpose |
|---|---|---|
| Google Analytics for Firebase | App interactions (for example, screens opened and features used), device and app information, app instance ID, advertising ID, approximate location derived from your IP address | Understanding how the App is used, improving features, measuring the effectiveness of our own advertising campaigns |
| Firebase Crashlytics and Performance Monitoring | Crash reports, diagnostics, performance data, device model and OS version | Detecting and fixing errors, improving stability |
| Firebase Cloud Messaging and Cloud Firestore (EU region) | Push notification token, app language, subscription status (free or PRO) | Sending notifications, including information about the App and special offers |
| Google Play Billing | Purchase and subscription status | Providing and verifying PRO subscriptions. Payments are processed by Google Play; we never receive your payment card details. |
| Google Ads | Analytics data described above, including the advertising ID | Measuring and improving campaigns that promote our own apps |
This data is not linked to your name, email address or contacts. Your events, notes, contacts, birthdays and voice notes are never included.
The free version of the App shows ads. A PRO subscription removes ads.
Ads are delivered through the AppLovin MAX mediation platform, which selects an ad from one of our advertising partners listed in section 15. To show ads, measure them and prevent ad fraud, AppLovin and the partner serving the ad may collect from your device:
Advertising partners never receive your events, notes, tasks, contacts, birthdays, voice notes or calendar data.
Depending on your choices (see section 8), ads may be personalized based on your interests or non-personalized. Each partner processes data under its own privacy policy, available on its website.
Before personalized ads are shown, we ask for your consent to use your data for personalized advertising and related purposes, using Google's consent tool, which is compliant with the IAB Transparency & Consent Framework. If you do not give consent, you will only see non-personalized ads. You can change your choice at any time in the App: About → Ad settings.
Data stored on your device remains under your control and is permanently deleted when you delete it in the App or uninstall the App. Events from calendar accounts on your device, including Google Calendar, are stored with their providers and can be managed or deleted there.
Analytics and crash data are retained according to Google's retention settings: event-level analytics data for up to 2 months, and user-level analytics data for up to 14 months from your last activity. Push notification tokens become inactive when you uninstall the App. Advertising partners retain data according to their own privacy policies.
Because the App has no accounts and the data we receive is not linked to your identity, we usually cannot identify data that belongs to a specific person. If you have a question about your data, contact us at management@plantech.app and we will do our best to help.
All data the App sends over the network is encrypted in transit using HTTPS/TLS. You can protect access to the App itself with a PIN code or biometric lock.
Google, AppLovin and our advertising partners may process data on servers located outside your country, including in the United States and other countries. These companies apply their own safeguards for such transfers, as described in their privacy policies.
Depending on where you live (for example, in the European Economic Area, the United Kingdom or California), you may have the right to access, correct or delete your personal data, to object to or restrict its processing, to withdraw consent, and to lodge a complaint with your local data protection authority. We rely on your consent for personalized advertising where required by law, on the performance of our agreement with you for subscriptions, and on our legitimate interest in operating, improving and promoting the App. To exercise your rights, contact us at management@plantech.app.
California residents: we do not sell your events, notes, contacts or other content. Sharing your advertising ID and related device data with advertising partners for personalized advertising may be considered "sharing" under California law. You can opt out at any time in the App (About → Ad settings) or by deleting your advertising ID in your Android settings.
The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will take appropriate steps.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page.
Ads in the App are mediated by AppLovin MAX (AppLovin Corporation, privacy policy). Ads may be served by AppLovin or by the following partners:
This list may change as we add or remove partners. Each partner's privacy policy is available on its website.
