Inkstep: Fill & Sign PDF

Inkstep fills and signs PDFs on your phone, and it works entirely offline. No account. No sign-up. No internet. The INTERNET permission is removed from the app, so Android itself will not let Inkstep open a connection — your documents cannot leave your phone, because there is nowhere for them to go. WHAT IT DOES • Sign a PDF or a photo. Share one to Inkstep from any app — WhatsApp, Gmail, Telegram, Files — or open one from your device. • Draw your signature once, with a finger or a stylus. It is saved and waiting the next time you need it. • Fill in the rest of the form: text fields, a date stamp, check marks and cross marks. • Scan paper with the camera. Point at a page and it becomes a PDF you can sign. • Send it straight back the way it came. BUILT FOR DOCUMENTS, NOT FOR DATA COLLECTION • No account, ever. • No analytics, no crash reporting, no tracking, no advertising ID. • No ads. • Your original file is never modified — Inkstep works on a copy of it. • Signatures and settings stay in the app's private storage on your device. Uninstalling Inkstep removes them. YOUR PDF STAYS A PDF Inkstep overlays your signature onto the existing page instead of flattening the document into a picture. Text stays selectable and searchable, and the file does not balloon in size. FREE, ALWAYS Unlimited signing • save to your device • share back • single-page scanning • date stamp • text fields and marks • one saved signature INKSTEP PREMIUM — ONE PAYMENT, NO SUBSCRIPTION • Unlimited saved signatures • Apply a mark to every page at once • Multi-page scanning One payment. Nothing renews. Everything you already use stays free. ABOUT THESE SIGNATURES Inkstep applies a visual electronic signature — the digital equivalent of ink on paper. It is not a certified digital signature (X.509 / eIDAS QES) and it makes no cryptographic authenticity claim. ABOUT SCANNING The scanner is provided by Google ML Kit and runs inside Google Play services. Scanning happens on your device and your scan does not leave it, but that component is Google's software under Google's privacy policy rather than ours. Every other part of Inkstep works without it.
