Non-disclosure agreements typically require the receiving party to protect confidential information with reasonable security measures, and a growing number of contracts now spell out specific requirements around device encryption and storage practices. For consultants and freelancers juggling documents from multiple clients on a single personal phone, keeping each set of confidential material genuinely protected is not automatic.
Common Ways NDA Documents Get Exposed
- Mail app attachments: PDF contracts and specs downloaded from email often stay cached in the Mail app and Files app indefinitely.
- Camera Roll screenshots: Quick screenshots of a client's contract or design mockup can end up backed up to iCloud alongside personal photos.
- Cross-client contamination: Working with multiple clients on one device increases the chance that one client's confidential material is visible while showing your phone to another.
- Device resale or handoff: Trading in or handing down an old phone without securely wiping every location a file was ever cached.
A Dedicated, Encrypted Space for Client Material
Stash lets you store any file type — PDFs, contracts, design files, spreadsheets — inside an AES-256 encrypted vault that's completely separate from your Mail, Files, and Photos apps, disguised behind a calculator, fitness tracker, or music player.
Keeping Each Client's Files Genuinely Separate
Because everything inside Stash is off the standard file system, there's no risk of one client's confidential documents surfacing in a Spotlight search or a shared Files app folder while you're working with another.
Removing the Cloud Backup Problem
Documents imported into Stash are never synced to iCloud or any other backup service, which matters for NDAs that specifically restrict where confidential material can be stored or replicated.
Deleting Cleanly When an Engagement Ends
Many NDAs require the return or destruction of confidential material at the end of a contract. Keeping documents inside a dedicated vault makes it straightforward to delete everything related to a specific client without hunting through Mail, Files, and Photos separately.
