PdfCraft — Privacy Policy

Last updated: 8 November 2026

PdfCraft is a PDF app for Android, published by appcraftstudio ("we", "us"). This policy explains what the app does and does not do with your information.

In short: your documents stay on your phone. Only when you use Ultra scan is a page image sent off the phone, to be read by Google's Gemini AI. To keep your Ultra scan balance we store an anonymous install ID with it. PdfCraft is free and shows ads served by Google AdMob; ads never receive your documents. We never sell your data.

Documents and files

When you choose a PDF or a photo, Android copies it into PdfCraft's own private storage area on your device. All editing — merging, splitting, rotating, watermarking, numbering, page removal, text editing, signing, converting PDFs to Word and normal scanning — happens locally on your phone.

Your documents are never uploaded to us. The only exception is a scanned page you choose to read with Ultra scan, below.
Signatures you draw or add are kept only on your phone, so you can use them again. You can delete them from the signature panel at any time.
Finished files are written to the app's private storage and handed to Android's share sheet only when you ask to share or save them. Where they go from there is your choice.
You can delete the app's files from within the app, or by clearing the app's storage in Android Settings. Uninstalling the app removes them all.

Ultra scan

Ultra scan turns a scanned page into editable text. When you start it, each page image is sent over an encrypted (HTTPS) connection to our server, which passes it to Google's Gemini API to read the text and layout. The result comes back to your phone. Our server does not store page images or their text. Google processes the image under the Gemini API Terms of Service.

If you add your own Gemini API key instead, pages go straight from your phone to Google under your key, and do not pass through our server. The key is kept on your phone only.

Your Ultra scan balance and purchases

Ultra scan is paid in page credits: every install gets a few free pages, and you can buy more or earn them by watching an ad. So that your balance survives reinstalls, the app creates an install ID: a one-way hash (SHA-256) of the device identifier Android provides to this app. It cannot be turned back into that identifier and is not linked to your name, email, phone number or Google account. Our server stores, against it:

your free and bought page balance, and a record of pages read, bought and refunded;
your Google Play purchase records: purchase token, order ID, product and credits;
a record of each free page earned by watching an ad: AdMob's transaction ID for the reward, the ad unit and the date.

Purchases are made and paid for through Google Play. We never see your card, UPI or other payment details, your name or your email. Our server checks each purchase with Google before adding credits, and checks daily for refunds.

PdfCraft is free to use and shows ads. Now and then, when you go back to the home screen after finishing a task, a full-screen ad may appear — never while you are working on a document. On the Ultra scan credits screen you can also choose to watch a short video ad to earn a free Ultra scan page, a few times a day.

The ads are provided by Google AdMob. When an ad is requested and shown, the Google Mobile Ads SDK collects and sends to Google information such as your device's advertising ID, IP address, device model and operating system, ad interaction data (for example, whether the ad was watched to the end) and approximate location derived from your IP address. Google uses it to show and measure ads, to prevent fraud and, where you allow it, to personalise ads — see How Google uses information from apps that use its services.
So a free page reaches the right balance, the app passes your install ID with a video ad you choose to watch, and AdMob sends it back to our server with a transaction ID when you finish the ad. We do not receive your advertising ID.
Your documents, scans and signatures are never shared with AdMob or with advertisers.
In the European Economic Area and the UK the app asks for your consent before showing ads, and Settings → Privacy choices for ads lets you change it. Anywhere, you can reset or delete your advertising ID, or opt out of personalised ads, in your phone's Settings → Google → Ads (or Settings → Privacy → Ads).

Document scanner

Scanning with the camera uses Google's ML Kit document scanner, provided by Google Play services. It runs on your phone and hands back only the pages you scan. Google may collect diagnostic and usage information about the scanner itself, under the Google Privacy Policy. Your scanned pages are not sent anywhere unless you choose Ultra scan.

Fonts

If you choose a font in the editor that is not already on your device, the app downloads it once from Google Fonts (fonts.gstatic.com). Only the font file is requested; your document is not sent. As with any web request, Google receives your IP address.

Who we share data with

We do not sell, rent or trade your data. It is handled only by the services that make the features work:

Google (Gemini API) — Ultra scan page images, to read them.
Cloudflare — hosts our server and its database: requests including your IP address, your install ID, balance and purchase records.
Google Play — purchases, purchase checks and refunds.
Google AdMob — ads, as described above.
Google Play services — the document scanner, as described above.
Google Fonts — font downloads.

We may also disclose information if the law requires it.

Permissions

PdfCraft requests:

INTERNET and ACCESS_NETWORK_STATE — Ultra scan, purchases, ads and fonts;
Google Play Billing — in-app purchases;
the advertising ID permission (AD_ID) and Android's ad services permissions (ACCESS_ADSERVICES_AD_ID, ACCESS_ADSERVICES_ATTRIBUTION, ACCESS_ADSERVICES_TOPICS) — used by Google AdMob for ads;
two that come with libraries the app is built on: FOREGROUND_SERVICE, used by Android's background task scheduler, and access to Google Play's install referrer service, which PdfCraft does not use.

It does not request access to your photos, files, camera, microphone, contacts or location: documents and photos are chosen through Android's own pickers, and scanning uses Google's document scanner or your phone's camera app, which hand back only the pages you scan.

Your choices

Don't use Ultra scan. Everything else in PdfCraft works without sending your documents anywhere.
Limit ad personalisation. Reset or delete your advertising ID, or opt out of personalised ads, in your phone's settings, as described under Ads.
See or delete your server data. Email us with the install ID shown on the Ultra scan credits screen and we will tell you what we hold or delete it within 30 days. Deleting it also removes unused credits.
Depending on where you live, laws such as India's Digital Personal Data Protection Act, 2023 or the EU GDPR give you further rights to access, correct or erase your data. Contact us to use them.

Children

PdfCraft is a general-purpose utility and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to this policy

If the app's behaviour changes in a way that affects this policy, we will update this page and change the date at the top before releasing that version.
