MetaGer.de is a German meta search engine with a focus on privacy and variety of results. With the MetaGer app you search the web optimally. The search saves your data volume and is tuned to unstable mobile connections.... Your MetaGer key for ad-free searches is anonymized by blind signatures when using the app.

MetaPurge is a privacy-first utility for locally stripping sensitive EXIF and metadata from your photos. Unlike other apps that just 'hide' tags, MetaPurge uses a 'nuclear' approach—it physically cuts the metadata segments out of the file bytes. Key Features: • 100% Offline: Your photos never leave your device. • Zero Permissions: No storage or internet permissions required on modern Android. • Format Support: JPEG, PNG, and WebP. • Smart Tools: Automatic orientation correction and high-res photo handling. • Transparent: Full technical metadata view for expert users. Keep your pixels, lose the tracking.

Protect your privacy by removing metadata from your photos, before sharing them on the Internet. Features: ✔️ View metadata ✔️ Image preview ✔️ Remove metadata ✔️ Simple and intuitive interface ✔️ Share directly from the app Learn more: Whenever you take a picture, additional metadata is saved in the image file. Most smartphones do not inform you about this. Metadata can look like this: 🕑 On which day was the picture taken, and at what time? 🗺️ And where exactly? 📷 Which camera or smartphone was used? 🔧 What camera settings were used? 📝 Notes of the photographer or the camera? 📌 More and more often, even exact GPS coordinates are saved in your photo. Metadata is sometimes very useful — for instance when sorting holiday photos. As soon as you share photos with others via social media, all this info is visible publicly. Data collectors and stalkers are more easily able to discover your place of residence or workplace from the metadata or draw conclusions about your daily routine. Tracking services create more comprehensive advertising profiles and sell your data to other organizations. Use the Metadata Remover to easily view all that data, remove it entirely, and then share the anonymized photo directly! That way you stay anonymous and safe on the Internet, while your friends can still admire your cute cat. Happy sharing! 😽

Features • Four colored noises and five ambient sounds, looped seamlessly. • Layer and mix ambient sounds, with quick presets. • Sleep timer with quick presets and custom hours/minutes/seconds. • Media-session integration: control playback from your lock screen, notification, or Bluetooth headset. • Works fully offline.

MetroVault turns an Android phone into a secure, air-gapped Bitcoin signing device like a cold-storage hardware wallet. It acts as an offline signer for your watch-only wallets (such as Sparrow, BlueWallet, or Electrum) running on an online device. Your private keys are generated and kept on a phone that never connects to the internet; all communication happens through QR codes, and network access is blocked at the Android level. Because the keys never touch an online device, the attack surface for theft and malware is dramatically reduced. MetroVault is fully open source and auditable, built on a custom Kotlin Bitcoin library so every cryptographic operation can be reviewed. Security * Air-gapped operation — designed for devices with no internet (airplane mode, Wi-Fi/Bluetooth off) * Dual-layer encryption — AES-256-GCM with PBKDF2 (210k iterations) plus the Android Keystore * Biometric unlock — hardware-backed fingerprint/face authentication * Plausible deniability — separate "Main" and "Decoy" wallets behind different passwords * Brute-force protection — exponential backoff with lockout, and an optional automatic wipe after repeated failed logins * Screenshots and screen recording are blocked app-wide Wallets * Single-sig and multi-sig (collaborative custody) support * Address types: Native SegWit (bc1q), Taproot (bc1p), Nested SegWit (3...) and Legacy (1...) * BIP-352 Silent Payments support, both to send to or spend from an SP wallet * BIP-39 passphrase support, saved locally or kept in memory only * BIP-85 derivation of child seeds and passwords * Custom entropy from dice rolls or coin flips, plus mnemonic checksum tools * Testnet4 support for testing Transaction signing * PSBT workflow (BIP-174) for single-sig and multi-sig * Air-gapped flow: scan PSBT, verify, sign, export — entirely by QR * Animated QR support: BC-UR (v1/v2) and BBQr for large transactions * On-device address verification and watch-only XPUB/descriptor export * Message signing and verification Permissions MetroVault requests only the camera (optional, for scanning QR codes) and biometric permissions. It has no internet permission and cannot connect to any network.

Metrodroid can read information from some public transport NFC smartcards. It was formerly known as Farebot M. This is a fork of Eric Butler's Farebot project, with support for additional cards and bug fixes. Supported cards: * Bilhete Único - São Paulo, Brazil (1) (2) (5) * Clipper - San Francisco, CA, USA * EZ-Link - Singapore (3) * Go card - Brisbane and South East Queensland, Australia (0) (1) (2) * Manly Fast Ferry - Sydney (and surrounds), NSW, Australia (0) (1) (2) * Matkakortti, HSL - Finland * Myki - Melbourne (and surrounds), VIC, Australia (0) (4) * MyWay - Australian Capital Territory, Australia (0) (1) (2) (5) * NETS Flashpay - Singapore * Octopus - Hong Kong (0) * Opal - Sydney, NSW, Australia (0) * ORCA - Seattle, WA, USA * OV-chipkaart - Netherlands (1) (2) * Shenzhen Tong - Shenzong, Guangdong Province, China (0) * SmartRider - Western Australia, Australia (0) (1) (2) * Suica, IOCOA, PASMO, Edy - Japan * Transit Access Pass - Los Angeles, CA, USA (0) (1) (2) (0): New in Metrodroid. (1): Not compatible with all devices (Mifare Classic). (2): Encryption keys are required to read this card. (3): Not compatible with all devices (CEPAS). (4): Only the card number can be read. (5): Fallback reader -- must be explicitly enabled in the application's preferences. You require a NFC-compatible phone in order to read cards. You need a NXP NFC chipset in your phone in order to read MIFARE Classic cards. Some phones have NFC chips from other manufacturers, which do not read Mifare Classic cards (eg: Nexus 4, Nexus 5, Samsung Galaxy S4). Check the About screen in the app in order to determine if your phone supports MIFARE Classic. Some agencies have encrypted cards. You will need to acquire encryption keys in order to read them. These are generally unique to each card. Sorry, I can't help you with this. Some other agencies' cards using Cubic Nextfare on Mifare Classic may also work.
