STACK Storage for iPhone

Handy, private cloud backups for iPhone

STACK Storage is a free iPhone app from TransIP BV that provides straightforward online file storage. Your data is kept on servers located in the Netherlands and protected with 256‑bit encryption so only you can open your files. The app makes it simple to upload, preview and send files to others, and it can automatically back up new photos and videos so your latest media is always preserved.

Main features and capabilities

• App-level password locks and in-app protection to keep content private
• Support for SFTP and WebDAV so you can connect with standard file tools
• Automatic photo and video uploads to maintain an up-to-date backup
• Optional two-step verification to add an extra layer of account security
• Access your documents from any location and device signed into the service
• Share and preview files easily with friends and family

Security and connectivity

STACK stores your files on Dutch infrastructure and uses strong, industry-standard 256‑bit encryption. You can enable two-factor authentication for the account, protect sensitive items with a passcode inside the app, and connect via SFTP or WebDAV if you prefer traditional file-transfer protocols.

Access, sharing and synchronization

The client lets you upload content, view it within the app and distribute links or files to others. Instant upload for camera items keeps a continuous backup of new photos and movies, and the service is designed to let you reach your files from anywhere you have an internet connection.

Support and responsiveness

TransIP advertises rapid customer service and aims to reply to inquiries within an hour. That quick turnaround, combined with straightforward app controls, makes STACK a reliable choice for users who want both usability and prompt support.

Alternative option

Consider VisualCV (free tier) if you’re also looking for a resume-building tool alongside cloud storage capabilities.
