How to Set Auto-Delete Timers in Edge-Drop
A clipboard shelf that never forgets is also a clipboard shelf that never stops accumulating. After a few weeks, the shelf holds a long tail of URLs, file paths, error logs, half-copied paragraphs, and the occasional secret that should have been redacted. Auto-delete timers are the routine hygiene layer: every unpinned item ages out on a schedule, and the user controls the schedule. This guide covers the four timer options Edge-Drop ships with, what happens to pins, how to pick a default, and how to combine timers with incognito and clear-on-restart. For the broader privacy stack see how to use incognito mode in Edge-Drop and how to clear unpinned history on restart.
The four timer options
Edge-Drop's auto-delete timer lives in the Behaviour tab of the settings panel. Four preset intervals are offered:
| Timer | Use case | Trade-off |
|---|---|---|
| Off (default) | Personal machine, single user, deep history useful | Shelf grows unbounded; sensitive items persist |
| 1 hour | Heavily shared workstation, regulated industry | Frequent useful items lost; pins required for anything reusable |
| 6 hours | Workday hygiene | Most of a day's copies available; next morning starts clean |
| 24 hours | Daily reset pattern | Yesterday's research is gone; today is fresh |
| 7 days | Light privacy posture | Most weekly context retained; long-tail secrets still age out |
The timer counts from when the item was captured, not from when Edge-Drop started. An item captured at 09:00 with a 6-hour timer expires at 15:00 the same day regardless of app restarts in between.
Picking a default is mostly a question of how sensitive the workflow is and how often history is actually reused. Most users settle on 24 hours as a sensible middle ground: the day's research is available all day, and the next day starts clean.
What happens to pinned items
Pins are the override. A pinned item does not age out, regardless of the auto-delete timer. Pinning is the right tool for:
- A URL you are actively researching
- A code snippet you will reuse across the session
- A file path you are working with for the day
- An image you are actively dropping into a deck
When you unpin an item, its original capture timestamp still applies. If the item is already past the timer threshold, unpinning causes it to be deleted on the next sweep. This is intentional: pinning is a "keep this" gesture, unpinning is a "let it expire normally" gesture, and the timer is the source of truth for "normally."
The pin/unpin control is on each item's context menu. For a walkthrough see how to pin and unpin items in Edge-Drop.
How the timer actually runs
Edge-Drop does not run a separate "deletion service." The clipboard poller, which runs approximately every 300 ms, also handles the timer sweep on a throttled cadence — typically once per minute. The sweep:
- Reads the current auto-delete setting (off, 1h, 6h, 24h, 7d).
- Iterates over the in-memory history list.
- For each unpinned item, checks whether
now - captured_at > threshold. - If yes, removes the item from history and from the on-disk encrypted store.
The store is rewritten on the next idle tick, so disk I/O is batched rather than per-item. This is why deleting 200 items at once is not noticeably slower than deleting 10 — the cost is the rewrite, not the per-item logic.
For the on-disk layout and what is encrypted, see where Edge-Drop stores data on disk.
How to pick a default
There is no universally correct timer. The decision tree:
- Is this machine shared with other users (family PC, lab machine, kiosk)? Use 1 hour, enable clear-on-restart, and disable cloud sync at the OS level. See shared Microsoft accounts and clipboard sync leaks.
- Is this a personal work machine handling customer data, credentials, or PII? Use 6 hours or 24 hours. Pin anything you need for the week.
- Is this a personal machine used mostly for browsing and writing? Use 7 days or off. Pin nothing routinely; rely on weekly review instead.
- Is this a developer machine handling production credentials? Use 1 hour or 6 hours, and pair with incognito for credential copies. See the env file should never touch history.
- Is this a design machine with heavy asset reuse? Use 24 hours, pin the active project's brand assets, and rely on building a personal sticker and icon kit for long-term storage.
The point of the timer is not to enforce a policy but to bound the worst case. Without a timer, a secret copied six months ago is still on the shelf. With a 24-hour timer, the same secret is gone by tomorrow.
Combining timers with other privacy controls
Auto-delete is one layer. The full hygiene stack:
- Auto-delete timer — bounds how long unpinned items live.
- Clear unpinned on restart — bounds how long unpinned items survive a reboot. Independent of the timer.
- Incognito — prevents capture entirely for a stretch. See how to use incognito mode in Edge-Drop.
- Pin only what you need — the weekly pin review pattern. See a weekly pin review beats infinite history.
- DPAPI at-rest encryption — protects history if the disk is read from outside Windows. Always on; not user-configurable.
The 10-minute end-of-day clipboard reset pattern — see the 10-minute end-of-day clipboard reset — pairs naturally with a 24-hour timer: the reset handles the immediate cleanup, the timer handles the case where the reset was forgotten.
Failure modes
A few behaviours to know about:
- Timer changes are not retroactive in the same sweep. If you change the timer from 7 days to 1 hour, items older than 1 hour will be deleted on the next sweep — usually within a minute. There is no grace period.
- Restarting Edge-Drop does not reset captured_at. The timestamp is part of the stored item, not the running process.
- Disabling the timer does not undelete. Items already swept are gone. There is no trash bin.
- Pinning during a sweep is racy but safe. If you pin an item in the same window as a sweep that would have deleted it, the pin wins. The sweep checks the pin flag at delete time.
- Image items use disk payloads. When an image item is deleted, the payload file is also deleted. There is no orphaned-image accumulation.
- Time-zone changes do not shift the timer. The timer uses monotonic timestamps internally; a clock change does not extend or shorten retention.
How to verify the timer is working
A simple test:
- Set the timer to 1 hour.
- Capture an item now and note the time.
- Wait — or temporarily set the system clock forward by 65 minutes if you need to verify immediately.
- Confirm the item is gone from the shelf.
- Pin another item, repeat step 3, confirm the pinned item is still there.
If the unpinned item is still on the shelf after the threshold, check that the timer setting saved correctly (close and reopen settings), that Edge-Drop is running, and that no other clipboard manager is shadow-capturing the same items.
What Edge-Drop does not claim
Auto-delete is local housekeeping. It does not:
- Erase the same copy from Windows clipboard history (Win+V) — that is a separate feature with its own clear controls.
- Erase the source app's undo buffer or internal log.
- Provide a forensic wipe. The DPAPI-encrypted store is rewritten, but disk-level forensic recovery of the previous store is theoretically possible until the sectors are reused. For pre-sale disk wiping, see how to wipe clipboard data before selling a PC.
- Send a remote-wipe signal. There is no cloud sync to wipe from.
For workflows that need a stronger guarantee (regulated industries, legal hold), Edge-Drop is not the right tool — that is a DLP/EDR product category. For an honest look at where Edge-Drop fits and does not, see when not to use Edge-Drop.
Summary
Auto-delete timers are the routine hygiene layer in Edge-Drop. Pick 1 hour for shared or regulated machines, 6 or 24 hours for personal work machines, 7 days for light personal use. Pin what you need to keep; let the timer sweep the rest. Combine with incognito for one-off secrets and clear-on-restart for shared-PC hygiene. The timer is one layer, not a complete privacy posture — but it is the layer that bounds the worst case without any ongoing effort from the user.
