MYContacts turns your contact details, your LinkedIn profile, or any web link into a clean, scannable QR code — created and stored entirely on your device. No account, no sign-up, no tracking. Open it and go. THREE KINDS OF QR CODE - Contact card — enter as much or as little as you like (name, title, company, phones, emails, website, socials, address, note, even a photo). The code holds a standard vCard, so one scan adds you to someone's address book. - LinkedIn — paste your profile or just your handle; scanning opens your LinkedIn. - Website / link — paste any URL (a site, booking page, portfolio, PDF, or app listing); scanning opens it. MAKE IT YOURS — COLORFY Style any code without losing scannability: solid colours or gradients, square / rounded / dot modules, custom finder corners, a transparent background, and a logo or short text in the centre. Pick from ready-made templates or build your own. Error correction is always set to the highest level so styled codes still scan reliably. SAVE, SHOW, SHARE - Save codes to your on-device library (My QR Contacts) and reopen them anytime. - Show full screen with the brightness boosted, so any camera reads it instantly. - Share the QR as a PNG, share a contact card as a .vcf file, or export your full setup as a JSON config you can re-import later. PRIVATE BY DESIGN Everything happens on your device. The app makes no network calls during normal use, includes no analytics or advertising, and asks for no permissions — it doesn't even need your camera or photo library (you pick a photo through the standard iOS picker). What you create never leaves your phone unless you choose to share it. FREE No purchases, no subscriptions, no ads. MYContacts is a free utility from MapYourTech, where optical and network engineers learn, practice, and advance.
