Privacy Policy
The short version
The PenguinPDF app processes your PDFs entirely on your device — we never see, upload, or store your files. The only personal data we collect is what you voluntarily send us through the contact form on this website. We don't run ads on the website, and we don't use tracking cookies.
1. Who we are
PenguinPDF is an independent Android application for annotating, filling, signing, and exporting PDF documents. This privacy policy covers both the PenguinPDF app and the penguinpdf.com website.
If you have questions about this policy, please contact us.
2. Information we collect
The app — almost nothing. PenguinPDF works entirely offline on your device:
- PDF files you open are read from and saved back to your device's local storage. They are never uploaded to our servers.
- We do not require an account and do not collect your name, email address, or device identifiers.
- We do not use analytics SDKs in the app.
The website — contact form only. When you use the contact form at penguinpdf.com/contact-us, we collect:
- Your name and email address (so we can reply)
- The subject and message text you write
- Your IP address (used by Cloudflare Turnstile for spam detection — see §4)
We do not use analytics, tracking pixels, or cookies on this website.
3. How we use your information
Contact form submissions are used solely to respond to your inquiry. We do not sell, rent, or share them with third parties for marketing purposes. Emails are stored in our inbox and deleted when no longer needed.
4. Third-party services
A small number of third parties are involved in delivering the app or website:
Google Play — The app is distributed through the Google Play Store. Google Play handles all payment processing for Pro subscriptions. Google's own Privacy Policy governs that relationship.
Google AdMob — The free tier of the app may display ads served by Google AdMob. AdMob may collect your device's advertising identifier (Android Ad ID) to serve relevant ads. You can opt out via Android Settings → Privacy → Ads. AdMob's ad policy applies. Pro subscribers do not see ads.
Cloudflare Turnstile — The contact form on this website uses Cloudflare Turnstile to prevent spam. Turnstile may analyse your IP address and browser signals to determine whether a submission is human. No persistent cookies are set. Cloudflare's Privacy Policy applies.
Google Fonts — This website loads the Nunito typeface from Google Fonts. Your browser makes a request to Google's servers for the font file. Google's Privacy Policy applies to that request.
5. Data retention
Contact form emails are kept in our inbox until no longer needed and are then deleted. We do not retain copies beyond that. Your PDF files are never in our possession and are therefore not subject to any retention policy on our part.
6. Your rights
Depending on where you live, you may have rights including access to, correction of, or deletion of personal data we hold about you (e.g. under GDPR or CCPA). Because we collect very little data, requests can usually be fulfilled quickly. Please contact us and we'll respond within 30 days.
7. Children's privacy
PenguinPDF is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has submitted information through our contact form, please contact us so we can delete it.
8. Changes to this policy
If we make material changes to this policy, we will update the effective date at the top of this page. We encourage you to review it periodically. Continued use of the app or website after changes constitutes acceptance of the updated policy.
9. Contact
Privacy questions or requests can be sent via our contact page. Please include "Privacy" in your subject line.
