How attachment expiry works

Fluxer automatically expires older attachments. Smaller files stay available for longer, while larger files expire sooner. If someone opens a message with a file close to expiry, we extend its availability so it remains accessible.

How expiry is decided

• The timer starts when you upload the file.
• Files 5 MB or smaller keep links for about 3 years (the longest window).
• Files near 500 MB keep links for about 14 days (the shortest window).
• Between 5 MB and 500 MB, larger files get shorter windows and smaller files get longer ones.
• Files over 500 MB are not accepted on the current plan.

Extending availability when accessed

If a message with a file is loaded and the remaining time is inside the renewal window, we move the expiry forwards. The renewal window depends on size: small files can renew up to about 30 days, while the largest files renew up to about 7 days.

One view is enough to refresh it. You don't need to click or download the file. Multiple views inside the same window do not stack. The total lifetime is capped to the size-based budget, so repeated renewals cannot keep a file available indefinitely.

What happens after expiry

We regularly sweep expired attachments and delete them from our CDN and storage. There can be a short delay between the expiry time and final removal.

Why we expire attachments

• Storage fairness: Large media is expensive to store indefinitely, so expiry helps keep storage fair for everyone.
• Safety and privacy: Clearing older uploads reduces the chance that sensitive files remain accessible longer than needed.
• Predictable limits: Clear timeframes help you plan and download what you want to keep.

Keeping important files

If a file matters to you, download it before it expires. For full account exports (including attachment URLs), see Exporting your account data.
