This Privacy Policy explains how the Diya: Photo Video Maker mobile
application (package com.ichime.photovideomaker, the “App”), published by Revolution Sport Company Limited (“we”,
“us”), handles information when you use it. By using the App you agree to this Policy.
You can use the App without creating an account. The photos and videos you select are processed entirely on your device to create your video. We do not upload, store, or transmit your photos, videos, or finished creations to our servers or to anyone else.
Optional sign-in. If you choose to sign in with Google (or Sign in with Apple on iOS), we receive your name, email address and a sign-in identifier from that provider through Firebase Authentication (Google). We use them only to keep your online invitations linked to you across devices. When you use an online feature without signing in, the App creates an anonymous identifier instead, which contains no personal details.
If you create an RSVP link for an invitation, the details you type for it — names, date, venue, an optional message and the App language — are stored in Google Cloud Firestore (Mumbai, India) and can be seen by anyone who has the link. Only share it with people you want to invite. Guests who reply enter their name, whether they will attend, the number of people and an optional note; these replies are visible only to you in the App. Guests do not need an account. Replies close 120 days after the link is created. You can delete an invitation and all its replies at any time in the App; deleting your account (Settings → Account) deletes all of them too. If you are a guest and want your reply removed, ask the host or contact us (see §12).
To sell and restore Premium, send festival reminders, measure installs and app performance, and fix crashes, the App and the third-party services below collect limited technical information. None of it includes your photos, videos or the text you type into them.
| Data | Why | Collected by |
|---|---|---|
| App usage & in-app events (e.g. screens viewed, a template opened, a video exported or shared), app-instance ID | Understand which features are used and improve the App | Firebase Analytics (Google) |
| Crash reports and diagnostics (stack traces, device model, OS version, app version) | Find and fix crashes | Firebase Crashlytics (Google) |
| Push messaging token; festival-reminder topic subscription | Send festival reminders you opted into | Firebase Cloud Messaging (Google) |
| Purchase and subscription status, an anonymous app user ID, store transaction IDs | Provide, validate and restore Premium | Google Play Billing (Android); Apple App Store (iOS) |
| Optional account: name, email address, sign-in ID; or an anonymous ID (only when you use online invitations) | Keep your invitations linked to you | Firebase Authentication (Google) |
| Invitation details you enter and your guests’ replies (see §1A) | Show your invitation page and collect RSVPs | Google Cloud Firestore |
| Install referrer (which link or campaign led to the install), install and in-app conversion events, purchase amounts, device and app identifiers | Measure which shares and campaigns bring new users (attribution) | Our attribution service (operated by us on Google Cloud) |
We do not collect precise location, contacts, microphone, or call data. The App reads your gallery only to let you pick media, and that media never leaves your device.
Our website photovideomaker.app (including its blog) uses Google Analytics (Google) to count visits and see which pages and links are used — for example, which page led to a tap on an app-store link. Google Analytics sets cookies and records the pages you view, the site that referred you, your browser and device type, and an approximate location (country and city) that Google derives from your IP address. We use this only to understand and improve the website. It is not linked to your App account, your purchases or your photos, and it is not used for advertising. You can block these cookies in your browser settings or install Google’s opt-out add-on (tools.google.com/dlpage/gaoptout).
The App does not show ads on any platform and contains no advertising SDK. It does not access your device’s advertising identifier (the Android Advertising ID or Apple’s IDFA), does not track you across other companies’ apps or websites, and so never shows Apple’s App Tracking Transparency prompt.
In-app purchases (Premium Monthly, Premium Annual, or a one-time Premium Lifetime — prices are shown in the App for your region) are processed by the store you installed the App from: Google Play Billing on Android, or Apple’s App Store in-app purchase on iOS. We never see or store your payment card details — those are handled entirely by Google or Apple. On Android, your Premium status is read directly from Google Play, which also restores it after a reinstall. On iOS, your Premium status is read directly from the App Store (StoreKit), which also restores it on a new device.
We do not sell your personal information.
We share the limited technical data above only with the service providers that make those features work: Google (Firebase Analytics, Firebase Crashlytics, Firebase Cloud Messaging, Firebase Authentication, Cloud Firestore, Play Billing, and Google Analytics for our website) and Apple (App Store in-app purchase, on iOS). Each processes data under its own privacy policy. Attribution data is processed by our own service. We may also disclose information if required by law.
On-device project data (your saved drafts) lives only on your device and is removed when you delete a project or uninstall the App. Analytics data is retained by the respective providers per their policies (typically up to 14 months for Firebase Analytics; configurable). Website analytics data is kept for at most 14 months under our Google Analytics data-retention setting. Purchase records are retained as long as needed to honour your entitlement and meet tax/accounting requirements. Invitations and their replies are kept until you delete them or your account. An optional account is kept until you delete it in the App.
Unless you use an optional account or online invitations, we hold no personal data about you; most data stays on your device or with the providers above. You can:
India (DPDP Act 2023): you have rights of access, correction, and erasure, and may raise a grievance with us at the contact below. EEA/UK (GDPR): our lawful bases are legitimate interests (analytics, security) and contract (purchases); you may lodge a complaint with your supervisory authority.
The App is intended for a general audience and is not directed to children under 13 (or the applicable age in your region). We do not knowingly collect data from children.
All network traffic between the App and our providers uses encryption (HTTPS/TLS). Premium status is re-verified with the store on each launch and is never trusted from unverified local storage.
We may update this Policy. Material changes will be reflected by the “Last updated” date above and, where appropriate, an in-app notice.
