Privacy Policy

Last updated 2 November 2026

Stow organises files on your Mac. This policy explains exactly what leaves your computer, what we keep, and for how long. It is written to be read, not to be survived.

1. What Stow sends when you organise a folder

To produce a plan, Stow sends the following for the folder you selected:

• File and folder names.
• A short excerpt of readable documents, at most the first 200 characters, used to work out what a file is about.
• For a file with no readable text, its general kind (image, archive, installer) in place of an excerpt.
• A brief technical description alongside each name: the file's type and size, when it was last changed, and for photos and video the dimensions, duration, and the capture time, camera and software recorded by the device that made it.

Stow never uploads your files. The file itself never leaves your Mac, and nothing at all is sent for a folder you have not chosen.

2. What we do not do with it

• We do not store the names or excerpts after your plan is returned.
• We do not use your content to train any model.
• We do not sell, rent, or share your content with advertisers.
• We do not read your files for any purpose other than producing the plan you asked for.

3. What we do keep

• Account, your email address, used to sign in and to contact you about your subscription.
• Device identifier, a one-way hash derived from your Mac, used to enforce the free trial and to stop one subscription being shared across many machines. It cannot be reversed into a serial number.
• Usage counts, how many organises you have run this period, and when. We record the count and the timestamp, not the folder, the file names, or anything about their contents.
• Billing records, handled by our payment processor. We never see or store your full card number.

4. Processing by third parties

Producing a plan requires third-party cloud infrastructure and language-processing providers acting as our processors under contract. They are permitted to process the data only to return your plan, and are contractually barred from retaining it or using it for their own purposes. Payment is handled by a third-party payment processor under its own privacy terms.

5. Retention

• File names and excerpts: not retained after the plan is returned.
• Usage counts: retained for the current and previous billing period, then deleted.
• Account and billing records: retained while your account is active, and for as long afterwards as tax and accounting law requires.

6. Your rights

You may request a copy of the personal data we hold about you, ask us to correct it, or ask us to delete your account and associated data. Email privacy@stowmac.com and we will respond within 30 days. If you are in the UK, EU or EEA you have these rights under the UK GDPR and GDPR respectively; if you are in California, under the CCPA.

7. Undo history and logs stay local

The record Stow keeps so it can undo a plan, which file moved where, is written only to your own Mac. It is never transmitted. It lives in a hidden .stow-history.json file inside each folder you organise, so uninstalling Stow does not remove it: delete that file from a folder if you no longer want the record of what moved there.

8. Children

Stow is not directed at children under 13 and we do not knowingly collect their data.

9. Changes

If this policy changes materially we will tell you by email before the change takes effect.

10. Who we are, and contact

Stow is made and operated by Aeroswipe LLC, a Wyoming limited liability company, which is the data controller for the personal data described in this policy.
