Portover is an offline contacts backup and phone-transfer tool for Android. Core purpose: read the contacts stored on the user's own device and turn them into a standard vCard (.vcf) backup file the user controls. FEATURES (free): back up all contacts to a .vcf file with no contact-count limit and no watermark; save the file to Downloads or any folder the user picks; send the file through the Android share sheet; restore by choosing a .vcf file, which Portover hands to the Android system Contacts importer; backup history (backups the user makes stay until the user deletes them); backup reminders; step-by-step guides; contact health and backup comparison counts. FEATURES (Portover Pro subscription): automatic weekly or monthly backups (newest 4, 8 or 12 automatic copies kept); missing-contact lists with a choice of who to bring back; full duplicate report and clean copy; fix lists; country codes in the backup copy; Excel, PDF and spreadsheet (.csv) exports; calendar and birthday backups (.ics); backing up chosen contacts or accounts; installed-app checklist with Play Store links; backup inspector with search and full card details; new phone checklist; storage view with a clean-up for old automatic backups; a warning before restoring on the same phone. MONETIZATION: auto-renewing subscriptions billed through Google Play Billing, weekly, monthly and yearly. Any introductory offer or trial, and every price, is shown by Google Play. No ads. No one-time purchases. No third-party ad or analytics SDKs. ACCOUNTS: there are no accounts. No sign-up, no login, no email collection, no user identifiers created by the app. PERMISSIONS: READ_CONTACTS (read-only) and READ_CALENDAR (read-only, for calendar backups), POST_NOTIFICATIONS (reminders and backup results the user turns on), RECEIVE_BOOT_COMPLETED and WAKE_LOCK (scheduled backups). The app does NOT request WRITE_CONTACTS or WRITE_CALENDAR. It does NOT request SMS, call-log, QUERY_ALL_PACKAGES or storage permissions. NETWORK: Portover's own code makes no network requests and there is no server for this app. The merged manifest contains the INTERNET permission only because Google Play's billing library adds it. Nothing about the user's contacts, calendar or backup files is uploaded, synced or transmitted by the app.
