Privacy Policy¶
Effective Date: September 2026
Thank you for using Handwriter (the "App"), provided by Androxus ("we," "us," or "our"). This Privacy Policy explains what the App collects, what it does not, and what you can switch off.
Overview¶
Handwriter turns text you type or paste into a handwritten-looking PDF, entirely on your device. It shows ads and uses Firebase for basic analytics and crash reporting.
The short version:
- Your documents are not collected. No text, image, custom font or exported PDF is ever sent to us
- Handwriter does not use OCR or AI to read, generate or process your documents
- No accounts, no sign-in, and we operate no server of our own
- Your drafts, exported PDFs, custom fonts and settings stay on your device
- Ads are off entirely for Pro users
What leaves your device¶
| What | When | Where it goes | Can you stop it |
|---|---|---|---|
| Standard app-usage data (app-instance identifier, device model, operating system version, approximate country) | Automatically, each time you use the App | Firebase Analytics | Not currently exposed as an in-app toggle |
| Advertising data (advertising ID, device and app information, IP address, ad interactions) | When an ad is shown | Google AdMob | Yes, buy Pro to remove ads |
| Crash and error reports | If the App crashes or hits a handled error | Firebase Crashlytics | Not currently exposed as an in-app toggle |
| Purchase information | When you buy Handwriter Pro | Google Play | N/A, handled entirely by Google |
Nothing on this list is the text, images or fonts inside your documents.
Your documents stay on your device¶
Handwriter formats the text you type or paste, using the font you choose, into a page styled to look handwritten, then exports it as a PDF. Inserting and recolouring images, applying page effects, and generating the finished PDF all happen on your device using Android's own graphics and PDF tools.
Handwriter does not use optical character recognition (OCR) or any AI service to read, generate or process your text or documents. It does not upload your typed or pasted text, your drafts, any image you insert, any custom font you upload, your page backgrounds, or your exported PDFs to Androxus or to any other server. Everything is read from and written to the App's own storage on your device, and you decide if and how to share a finished PDF.
Advertising¶
The App shows ads from Google AdMob: an app open ad, and an interstitial ad while your PDF is being generated. Buying Handwriter Pro removes ads entirely.
When an ad is requested, AdMob may receive your advertising ID, device and app information, IP address, and your interactions with the ad, and may use them to personalise advertising. See the Google Privacy Policy and how Google uses data from partner apps.
Analytics¶
The App uses Firebase Analytics to understand basic usage, such as how often the App is opened. This is Firebase's standard automatic collection: an app-instance identifier, device model, operating system version, and an approximate country derived from your IP address.
Handwriter's own code does not send any custom event describing what you write, which font or feature you use, or what's in your documents.
Crash reporting¶
The App uses Firebase Crashlytics in release builds to record crashes and handled errors. A crash report contains a stack trace, device model, operating system version and app state at the time. It does not contain the text, images or fonts in your documents.
Crash reporting is not currently exposed as a user-facing toggle. If you would prefer not to send crash reports, contact us.
Purchases¶
If you buy Handwriter Pro, the transaction is handled entirely by Google Play. We never see or receive your payment details. See the Google Play Privacy Policy.
Permissions¶
| Permission | Which feature needs it | What happens to the data |
|---|---|---|
| Internet | Ads, Firebase, Google Play Billing | See the table at the top |
| Photos and storage | Inserting an image into a page, choosing a custom page background, picking a custom font file, and saving or opening exported PDFs | Files are read and written on your device only. Never transmitted |
| Advertising ID | Added automatically by the Google AdMob library | Used to measure and personalise ads. See Advertising above. You can reset or limit it from Android Settings → Privacy → Ads |
Handwriter can also check whether the Androxus PDF Reader app is installed, so it can offer to open an exported PDF directly in it, and whether a small number of other Androxus apps are installed, for the "Check out our other apps" links in About. This does not let the App see your full list of installed apps.
What's stored on your device¶
Your documents and drafts, any custom fonts, images or backgrounds you add, your exported PDFs, and your app settings are all kept in Handwriter's own storage on your device. None of it is uploaded automatically.
Data we do not collect¶
To be explicit, Handwriter does not collect, store off device, or transmit to us:
- The text you type or paste into a document
- The content of any image, font or background you add
- Your drafts or exported PDFs
- Your contacts or precise location — Handwriter does not request access to either
- Your name, email address or any account identity

Because we hold no account and run no server, there is no profile of you for us to export or erase. Data held by Google as a result of ads, analytics or crash reporting is subject to Google's own controls.
Children's Privacy¶
Handwriter is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us.
