Khmer Calendar Pro+ (iOS)
Last updated: July 30, 2026
Your privacy is fundamental to our design. Khmer Calendar Pro+ ("the App") by Rottnak Labs / Leang Rottnak keeps most of your information on your device. This policy explains what stays local, what may leave the device through Apple or third-party services, and how to contact us.
Privacy at a Glance
1. Information Stored on Your Device
The App stores the following locally. We do not operate a first-party server that receives this content:
- Reminders & notes: Titles, note text, dates, alert offsets, repeat rules, and categories (for example personal tasks or leave).
- Leave types: Names and colors you configure for day-off planning.
- Preferences: Language (Khmer / English), appearance, day-type colors, tab order, weekend settings, and calendar event filters.
- Location preference (not GPS): The Cambodia province and district you select for weather and sunrise/sunset. The App does not request device Location Services permission.
- World clocks: Up to two saved city/timezone choices.
- Weather cache: Recent weather and forecast data for your selected district.
- Widgets: A snapshot shared with the widget extension through the App Group
group.com.rottnaklab.KhmerCalendarProso calendar and reminder widgets can update on the Home Screen. This sharing is on-device only. Snapshots may include holiday or reminder titles needed to render the widget.
Deleting the App removes this local data (including App Group data associated with the App). An active Apple In-App Purchase subscription is managed by Apple and is not deleted when you remove the App — manage or cancel it in Subscriptions.
2. Permissions
Notifications
With your permission, the App schedules local notifications for holiday and personal reminders (alerts, sound, and badge). Notification content is generated on your device (and may include reminder titles you set) and is not sent to our servers.
App Tracking Transparency
On supported iOS versions the App may ask for tracking permission (including for users who later purchase Premium). The system prompt uses this purpose string:
“Your data will be used to deliver personalized ads and experience while keeping the calendar free to use.”
If you decline, ads may still appear in a non-personalized form when the free tier is active. Premium removes ads; declining ATT only affects whether ads can be personalized.
Location
The App does not request GPS or Location Services. Weather and sun times use the coordinates of the Cambodia district you choose in Settings.
3. Information Processed Through Apple & Partners
Partners below process data under their own terms and privacy policies. We do not control how long they retain information. Some processing may occur outside Cambodia (for example PostHog’s US endpoint and Google advertising infrastructure).
Apple WeatherKit
When weather is enabled for your selected district, the App requests weather from Apple WeatherKit using that district’s coordinates. Apple processes the request under Apple’s terms and privacy policy. Attribution may link to Apple Weather legal pages.
StoreKit / Premium
Optional Premium is sold through Apple In-App Purchase (monthly product
com.rottnaklab.khmercalendarpro.monthly). Premium currently removes ads; calendar features
remain available without purchase. Payment details are handled by Apple. We do not receive your credit
card number. Purchase/restore status is used only to unlock Premium on your device.
Google Mobile Ads (AdMob)
The free version may show advertisements via Google AdMob. AdMob may use device advertising identifiers (such as IDFA when tracking is allowed), SKAdNetwork, and related measurement technologies subject to your ATT choice and Google’s policies. Tracking-related domains declared in our privacy manifest include doubleclick.net, googlesyndication.com, and googleadservices.com.
PostHog (analytics)
We use PostHog (https://us.i.posthog.com) for product analytics to understand feature use
and improve the App. Events may include app opens, onboarding steps, language or region preference
changes, tab usage, paywall views, subscription purchase/restore outcomes, notification permission
results, and high-level reminder actions (for example created/deleted). Properties may include language,
selected province and district (ids and English names), climate zone, and Premium status. Analytics may
be processed in the United States.
We do not send the full text of your personal notes or reminder bodies to PostHog as analytics content. Session replay and similar invasive capture features are disabled in our configuration.
Apple App Store diagnostics
If you share analytics with Apple, Apple may provide crash and performance diagnostics according to your iOS settings and Apple’s privacy policy.
4. What We Do Not Do
- We do not require an account or social login.
- We do not sell or rent your personal data.
- We do not operate a cloud backup of your reminders, notes, or settings on Rottnak Labs servers.
- We do not currently access Apple Calendar (EventKit) or upload your calendar events.
- We do not collect birth-chart profiles, “bonds,” or horoscope compatibility data — those are not part of Khmer Calendar Pro+.
5. Children’s Privacy
The App is a general-audience productivity calendar. We do not knowingly collect personal information from children for the purpose of selling data or creating profiles beyond the limited advertising and analytics described above.
6. Changes
We may update this policy as the App evolves. The “Last updated” date at the top will change when we do. Continued use of the App after an update means you accept the revised policy.
7. Support & Contact
For technical support, feature questions, or privacy inquiries:
Email: leangrottnak@gmail.com
You can also open Support from the App’s Settings. Messages may include your app version and language to help us help you.
