Effective date: 11 November 2026 (updated for version 0.2: suggestions, votes, instant notifications and ads)
Mehndi Design ("the app") gives you mehndi (henna) design ideas. You can browse designs by hand part, time, style and occasion, save the ones you like, try a design on a photo of your own hand, watch a design built up step by step, practise tracing it with your finger, follow a 30-day course, and use a timer that tells you when to remove the paste.
We, the developer, collect no personal data: there is no account, no login and no analytics. The app shows ads from Google AdMob, and Google collects some data to show those ads (see "Ads" below); we never see it. The other exceptions are a suggestion you choose to send, which contains only what you type, and an anonymous vote (both below).
The app is free and shows ads from Google AdMob: a small banner below the app, and an optional short video before saving a design to your gallery (you can tap "No thanks"). To show and measure ads and to prevent fraud, Google and its partners may collect and use your device's advertising ID, your IP address (and the approximate location it suggests), information about your device and the app, and how you interact with the ads. Ads are limited to content suitable for all ages. We never receive this data.
In the EEA, the UK and Switzerland the app first shows Google's consent form; you can change your choice any time in Settings → Ad privacy choices. Everywhere, you can reset or delete your advertising ID in Android settings (Privacy → Ads). More: how Google uses information from apps that use its services.
When you open the app with an internet connection, it downloads the current list of designs, any new design pictures, update notices and announcement popups from our website, mehndi.nareshbasude.in, so they also work offline later. The app sends nothing about you in these requests. Like any website, our server keeps standard technical logs of requests (such as IP address, time and app version) to keep the service running and secure; these are not linked to you and are not shared or sold.
In Settings → "Send a suggestion" you can write to us, for example to ask for a kind of design or to tell us about a problem. Nothing is sent until you tap "Send". We receive only: the text you wrote, the type you picked (design request, idea, problem or other), the app version and the app language. No name, phone number, email, account or device ID is attached, and the app asks you not to write personal details in the message.
Suggestions are stored privately on our server and read only by the developer, to decide which designs to add and what to fix. They are never sold or shared. To stop spam, our server keeps a scrambled (one-way hashed) form of the sender's internet address for one hour and limits how many suggestions can be sent per hour; after that hour it is deleted. Because suggestions are anonymous, we cannot reply to them or link them to you. Old suggestions are deleted from the inbox by the developer.
The mehndi course is not ready yet. On the Course screen you can tap "Bring it quickly!" to tell us you want it. That sends one anonymous count ("course") and the app version, nothing else: no name, account or device ID. We only see how many taps there were per day, which helps us decide what to build first. The same one-hour anti-spam check as for suggestions applies.
If you allow notifications, the app receives notices such as "new bridal designs added" instantly through Firebase Cloud Messaging, a Google service. For this, Firebase gives the app on your phone a random ID (a Firebase installation ID and a push token), which Google uses only to deliver the messages. Our server never receives or stores this ID: every phone joins the same group (a "topic") and we send one message to the whole group. Firebase is switched on only after you allow notifications; if you never allow them, no ID is created. The app uses no Firebase Analytics and no advertising ID. See Google's privacy policy and Firebase privacy.
As a backup (for example on phones without Google Play), the app also checks a small public file on our website about once an hour. That check is the same for everyone and sends nothing about you. You can turn notifications off any time in Settings → Notifications, or in Android's settings for the app.
When you use "Try on my hand", you pick a photo with Android's own photo picker. The app only receives the one photo you select, shows it on screen and never uploads, copies or keeps it. When you tap "Save picture", the finished picture is saved to your phone's gallery (Pictures/Mehndi), where only you control it.
Your saved designs, your practice drawings, your course progress, the timer and your settings (language, theme, level) are kept only in the app's private storage on your phone. They are removed when you uninstall the app, or when you use "Reset app" in the app's Settings.
If Android backup is switched on for your phone, Android may include this data in your phone's own backup to your Google account. That backup is made and controlled by Android and your Google account settings; the developer never receives or sees it.
Internet, to download new designs, update notices and notifications, and to send a suggestion when you tap "Send". Notifications (Android 13 and newer ask you first), only to show notices about new designs; the standard Firebase Cloud Messaging permissions to receive them (receive messages, keep the phone awake briefly, check the network). Run at startup (RECEIVE_BOOT_COMPLETED), only so the hourly notification check stays booked after your phone restarts. Advertising ID (AD_ID), used only by Google AdMob for ads. The app has no access to your camera, microphone, location, contacts or files. Choosing a photo uses the system photo picker, and saving a picture uses Android's standard gallery storage, neither of which needs a permission.
If you tap "Send to my mehndi artist" or "Share", Android's own share sheet opens with the design picture and a short line of text. Nothing is sent unless you choose an app to share it with, and the developer never receives it.
"Save to gallery" saves a copy of the design picture to your phone's gallery (Pictures/Mehndi).
The app is not directed at children under 13. Apart from the data Google uses for ads (above) and a suggestion or vote someone chooses to send, we collect no data from anyone, of any age.
If the app ever changes in a way that affects privacy, this page will be updated and the effective date changed.
