Clean up your contacts without breaking your address book. Contactio scans your contacts on your device, finds duplicates and fixes broken entries. Everything stays local. No cloud upload. No tracking. Merges the safe way Contactio treats a shared MOBILE number as the proof that two entries are the same person. A landline or a company switchboard that colleagues share never links two different people, so a merge never sweeps up someone who just works in the same office. Before anything changes you see exactly which phone numbers and emails are kept, and you can leave any out. What it does • Finds duplicates by name, phone, email and other details • Shows exactly what will be kept before you merge, and lets you leave out values • Merges in one safe step: phone numbers, emails, addresses and other details are carried over • Fixes missing names, missing phone numbers and organizations guessed from email domains • Cleans broken names with extra spaces, odd characters or wrong casing • Standardizes different spellings of the same organization • Searches across results by name, company, phone or email, including Turkish letters Safe by design • A backup is saved before every change, and deleting always backs up first • Undo any merge, fix or delete from the Merge Archive • Restore from a backup file at any time; restoring twice never adds copies • Limits large changes: it will not delete or change more than 40% of your contacts at once • Works with limited contacts access and tells you when results may be incomplete Private • All processing happens on your device • No account, no cloud upload, no data sharing • Your backups are .vcf files in the app's own folder, and you can delete them in Settings Available in English and Turkish.
