If local law requires a higher minimum age for certain services, advertising, purchases, or consent, those requirements also apply.
You are responsible for ensuring that your use of the App is lawful in your country or region.
4. No User Account Required
Sri Lanka Calendar does not currently require you to create an account.
The App does not currently provide:
- username/password accounts;
- Google sign-in;
- email-based login;
- cloud user profiles; or
- account-based synchronization.
Certain functionality, such as Google Play purchases, may nevertheless depend on your Google Play account.
Your relationship with Google in connection with your Google account and Google Play purchases is governed by Google's applicable terms.
5. Calendar and Holiday Information
Sri Lanka Calendar provides information about Sri Lankan holidays, Poya days, public holidays, bank holidays, mercantile holidays, and other special dates.
We make reasonable efforts to provide accurate and up-to-date information.
However, holiday information may be:
- changed by government authorities;
- declared after an App release;
- amended;
- rescheduled;
- subject to regional or institutional differences; or
- affected by errors in external sources or data feeds.
Therefore, calendar and holiday information provided by the App is for general informational and convenience purposes.
You should verify important dates with the relevant official authority before making decisions involving:
- legal deadlines;
- banking;
- employment;
- school schedules;
- business operations;
- travel;
- financial transactions; or
- other important commitments.
Arvin Apps does not guarantee that every calendar entry will always be complete, current, or error-free.
6. Holiday Data Synchronization
The App may download holiday information from online resources hosted by Arvin Apps, including data hosted using Firebase Hosting.
The App may periodically check whether newer holiday data is available.
Holiday information may be downloaded by year and stored locally on your device.
Internet access may be required for:
- initial holiday synchronization;
- updating holiday information;
- downloading future-year data; and
- checking whether updated holiday data is available.
If internet access is unavailable, the App may continue using previously downloaded local data where available.
We do not guarantee that holiday synchronization will always be available without interruption.
Synchronization may fail because of:
- network problems;
- hosting outages;
- device restrictions;
- corrupted data;
- maintenance;
- third-party service outages; or
- other technical issues.
7. Personal Events
The App allows you to create personal calendar events.
You may be able to:
- create an event;
- specify an event date;
- edit the event name;
- change the event date; and
- delete the event.
Personal events are currently stored locally on your device.
Sri Lanka Calendar does not currently upload your personal event names or personal-event dates to Arvin Apps' servers or Firebase.
Because personal events are stored locally, they may be lost if you:
- uninstall the App;
- clear the App's storage;
- reset your device;
- lose your device;
- experience device or storage corruption; or
- otherwise remove the App's local data.
Unless a separate backup feature is introduced in the future, Arvin Apps is not responsible for recovering lost personal events.
8. No Google Calendar Synchronization
Sri Lanka Calendar does not currently synchronize personal events with Google Calendar or another external calendar provider.
Events created inside Sri Lanka Calendar should not be assumed to exist in your Google Calendar, workplace calendar, or any other calendar service.
Likewise, external calendar events should not be assumed to appear in Sri Lanka Calendar.
9. Notifications and Reminders
The App may allow you to enable reminders for:
- Sri Lankan holidays; and
- personal events.
Depending on available settings, you may be able to choose:
- whether reminders are enabled;
- how many days before an event a reminder should appear; and
- the time at which reminders should be shown.
These reminders are generated locally by your device.
Reminder delivery can be affected by Android system behavior, including:
- notification permissions;
- battery optimization;
- background restrictions;
- Doze mode;
- device manufacturer restrictions;
- operating system updates;
- notification settings;
- device restarts;
- time-zone changes; or
- user configuration.
For this reason, we do not guarantee that every reminder will be delivered at the exact requested time.
You should not rely on Sri Lanka Calendar as the sole reminder system for critical events, appointments, deadlines, payments, medical matters, legal matters, or other important obligations.
10. Home-Screen Widgets
Sri Lanka Calendar may provide Android home-screen widgets.
Widget functionality may include:
- displaying a monthly calendar;
- displaying upcoming events;
- showing holidays;
- showing personal events;
- moving between calendar months; and
- returning to the current date.
The App may provide different widget styles, including Classic and Glass styles.
Widget behavior can vary depending on:
- Android version;
- launcher;
- screen size;
- manufacturer;
- device settings; and
- operating system restrictions.
We do not guarantee identical appearance or behavior on every device or launcher.
12. Advertising
Sri Lanka Calendar may display advertisements.
Ad formats may include:
- banner ads;
- native ads;
- interstitial ads; and
- other supported formats introduced in future versions.
Advertising may be provided through third-party services including:
- AppLovin MAX;
- Meta Audience Network; and
- advertising networks made available through the mediation platform.
Advertisement availability, frequency, content, and targeting may vary.
Arvin Apps does not directly control every advertisement displayed through third-party advertising networks.
13. Personalized and Non-Personalized Advertising
Depending on:
- your region;
- applicable law;
- consent choices;
- advertising settings; and
- ad-network availability,
the App may show personalized or non-personalized advertising.
Where required, the App may use a Consent Management Platform (“CMP”) to request or manage your advertising consent.
If you decline consent for certain advertising purposes, the App may continue to display non-personalized or contextual advertising where permitted.
14. Third-Party Advertisements
Advertisements shown in the App may promote third-party products, websites, applications, or services.
Arvin Apps does not endorse every product or service advertised.
If you interact with an advertisement, you may be redirected to a third-party service.
Your use of that third-party service is governed by its own:
- terms;
- privacy policy;
- purchase conditions; and
- security practices.
Arvin Apps is not responsible for losses, disputes, purchases, services, content, or transactions between you and third-party advertisers.
15. Remove Ads Purchase
Sri Lanka Calendar may offer a one-time Remove Ads purchase.
If offered, after a successful purchase, advertising may be removed from eligible areas of the App.
Some non-advertising content, notices, third-party links, or other elements may continue to appear.
If offered, the Remove Ads purchase:
- is not currently a subscription;
- is processed through Google Play;
- does not provide ownership of the App;
- does not automatically unlock every premium feature unless expressly stated; and
- may be associated with the Google Play account used to make the purchase.
16. In-App Purchases
The App may provide one-time purchases, including:
- Remove Ads;
- premium widgets; and
- other optional premium features introduced in the future.
Unless specifically stated otherwise, purchases are one-time purchases and not subscriptions.
If purchases are offered, transactions will be processed through Google Play Billing.
Arvin Apps does not directly collect your credit-card or payment-account information.
Google may process:
- payment details;
- transaction information;
- purchase history;
- account information; and
- related billing information.
Google's terms and policies govern the payment transaction.
17. Pricing
Prices for paid features may:
- vary by country;
- be displayed in local currency;
- include or exclude taxes depending on Google Play rules;
- change over time; and
- be affected by exchange rates or Google Play pricing systems.
The price shown through Google Play at the time of purchase is the applicable purchase price.
18. Refunds
Refunds for purchases made through Google Play are generally subject to:
- Google Play refund policies;
- applicable consumer protection laws; and
- any additional rights available in your jurisdiction.
Arvin Apps does not directly control Google's payment-processing or refund systems.
Where appropriate, users should submit refund requests through Google Play.
19. Restoring Purchases
The App may verify previously purchased premium features through Google Play.
Purchase restoration may depend on:
- using the same Google Play account;
- Google Play services being available;
- the transaction remaining valid; and
- Google's purchase-verification systems.
We do not guarantee that purchases can be restored across unrelated Google accounts.
20. Firebase Analytics
The App uses Firebase Analytics to help us understand how users interact with the App.
This information may be used to:
- understand feature usage;
- improve navigation;
- identify frequently used functionality;
- measure releases;
- improve user experience; and
- guide future development.
Analytics data is not intended to store your locally created personal calendar-event content.
21. Crash Reporting
The App uses Firebase Crashlytics.
Crashlytics may automatically collect technical information when the App crashes or encounters certain errors.
This information helps us diagnose and correct defects.
We cannot guarantee that every software defect will be identified or resolved.
22. Performance Monitoring
If included in a future version, the App may use Firebase Performance Monitoring.
This may be used to measure technical performance including:
- application startup;
- network request performance;
- responsiveness;
- latency; and
- other technical measurements.
This information is used to improve App performance and reliability.
23. Remote Configuration
Sri Lanka Calendar may use Firebase Remote Config.
Remote Config may allow us to change certain non-sensitive App settings or feature configurations without requiring an immediate new App release.
This may include:
- feature availability;
- presentation settings;
- technical configuration; or
- rollout-related settings.
Remote Config does not provide us with the ability to remotely access your locally stored personal events.
24. Internet Connection
Some features require internet access.
These may include:
- holiday updates;
- Firebase services;
- advertising;
- purchase verification;
- remote configuration; and

We aim to provide useful translations of the App interface.
However, translations may contain errors, differences in terminology, or inconsistencies.
Where a translation differs materially from the meaning intended by the App's underlying functionality, the technical behavior of the App takes precedence.
Users are welcome to report translation issues to:
apps.arvin@gmail.com
