Privacy

Your clipboard stays yours.

Stowpad treats copied content as sensitive by default: encrypted on your Mac, excluded from cloud services, and controlled by you.

Last updated: 19 August 2026

01The short version

Stowpad is a local-first clipboard manager for Mac. Saved clipboard contents are encrypted on your Mac, and Stowpad does not send clipboard content to a cloud service.

Smart Features are optional. Protected clips are excluded from search indexes, suggestions, OCR-derived metadata and model requests.

Stowpad has no accounts and no sign-in, collects no analytics, and contains no advertising or tracking code. Exactly one feature reaches a server outside your Mac — looking up a reference at doi.org, described in section 06 — and it only runs when you ask for it.

02Clipboard history

Clipboard history, attachments, source-app context, paste-learning events and local smart indexes are encrypted at rest. The encryption key is stored in your login Keychain.

File clips are decrypted only into an owner-only temporary paste directory and removed shortly after paste. Stowpad does not log raw clipboard contents or encryption keys.

03Protected apps

You can mark apps as protected. New clips copied from those apps hide their contents and require Touch ID or your Mac password before paste.

Protected clips are not indexed, suggested, used for paste learning or sent to an on-device language model. Protecting an app also removes its retained smart metadata from existing clips.

04Screen text and table capture

Stowpad requests Screen Recording permission only when you capture screen text or pick a colour from the screen. The selected region is processed locally with Apple Vision and is not saved as a screenshot file. Colour picking keeps the sRGB value only.

Vision can recover a table and present it as Markdown, CSV, TSV, LaTeX or Booktabs. No generative model sees the image. Captures from protected apps take the redacted protected-clip path.

05Smart Features

Smart Features are opt-in. Apple Intelligence is the default generative provider and runs on this Mac. Stowpad does not use Private Cloud Compute or any cloud-model provider.

Ollama is an optional alternative that is off by default. It is a separate process on this Mac and requires an explicit disclosure before use. Stowpad restricts it to 127.0.0.1, disables system proxies, sends no credentials or cookies, and cannot be configured with a remote host.

Turning Smart Features off immediately removes derived smart indexes, source-app identifiers and paste-learning events while keeping ordinary history, pins, collections and tags.

06References and reference lookup

Stowpad can recognise a reference identifier — a DOI, an arXiv id, an ISBN — in something you copied. Recognising it, and formatting a citation from what you already have, happen on your Mac and need no network.

Looking a reference up does not. When you press Look Up, Stowpad sends that identifier, and nothing else, to doi.org. It sends no account, no cookie, no device identifier and no other part of the clip. doi.org sees the identifier and the IP address making the request, so over time it can tell which papers were looked up from that connection. Stowpad asks for your agreement before the first lookup. A lookup happens only when you press Look Up — never on capture, never when a rule files a clip, and never in the background.

07Purchases

Stowpad Pro is sold only through the App Store. Apple handles the transaction, and Stowpad never sees, receives or stores your payment details, your Apple Account or your billing address.

Whether you have Pro is answered by Apple's signed subscription status, checked each time Stowpad launches. Stowpad records nothing about your subscription of its own — no trial marker in preferences, no keychain entry, no device fingerprint — which is also why a reinstall on the same Apple Account restores what you paid for and does not hand out a second free trial.

08How long things are kept, and how to remove them

Stowpad keeps clipboard history until something removes it, and everything that removes it is yours to trigger. There is no server copy and no backup held by us, so deleting on your Mac is deletion.

You can delete a single clip from the panel, clear the whole history from Settings › General, or set an automatic schedule there — on quit, daily, weekly, fortnightly, monthly, or on days and a time you choose. A scheduled or on-close clear leaves Locked History in place; only Clear All Clipboard History removes it. Clearing history also clears the current system pasteboard. Free users keep the newest 30 clips usable; older clips stay encrypted in Locked History and remain exportable. Settings › Stowpad Pro shows how many and can permanently delete them.

Export requires Touch ID or your Mac password. The file you save — CSV, plain text or JSON — is not encrypted by Stowpad.

Turning Smart Features off immediately erases the derived data they created — smart indexes, source-app identifiers and paste-learning events — while leaving your ordinary history, pins, collections and tags alone. Removing Stowpad removes its encrypted store with it; deleting its key from your login Keychain makes any remaining copy unreadable.

Because Stowpad holds nothing about you on a server, there is no data for us to delete on request and no account to close. If you would like that confirmed in writing for your own records, ask.

09This website

This marketing website uses Microsoft Clarity to understand how visitors use it — pageviews, clicks and scrolling, aggregated across sessions. Clarity sets cookies and sees your IP address and browser details while you're on this site; it never receives anything from the Mac app itself, which contains no analytics or tracking code of any kind.

No third party receives anything about you from the app. The website's analytics provider is Microsoft Clarity, and nothing else: no mailing list, no advertising network, no affiliated company with access to anything beyond the aggregated usage data described above.

Your browser's ordinary request to our host — the page you asked for, your IP address, the time — is what any web server sees in order to answer it. It is not joined to anything, not profiled and not passed on.

10Your control and contact

Every optional part of Stowpad can be turned back off, and turning it off is what withdraws your agreement to it: Smart Features, Ollama and reference lookup each stop immediately and, where they created data, erase it. Permissions you granted macOS — Accessibility for auto-paste, Screen Recording for text capture and colour picking — can be revoked at any time in System Settings › Privacy & Security, and Stowpad keeps working without them.

Stowpad is not directed at children and collects nothing that would identify anybody, of any age.

Privacy questions, and requests for written confirmation of any of the above, can be sent to hello@stowpad.app. If this policy changes, the date below changes with it, and any change that affects what leaves your Mac will be described in the app before it takes effect.
