01Our guiding principle
Prompto is a local-first app. Your prompt library, your tags, your usage patterns, and your settings all live on your Mac — in a folder you own, in a file format you can read. We cannot see them because we don't operate a server that receives them.
This isn't a policy decision that could change tomorrow; it's how the software is architected. There is nowhere for your prompts to go except the disk they were typed on.
Prompto does not collect, transmit, or have access to your prompts, tags, search queries, or usage data.
02Data we do not collect
To be unambiguous, Prompto does not collect any of the following:
- The content of your prompts, titles, descriptions, or tags.
- Your search queries or which prompts you use most.
- How often you open Prompto or which shortcuts you use.
- Your Mac's name, hardware identifier, IP address, or location.
- Any list of other apps installed on your Mac.
We do not have accounts. You do not sign in. We never ask for your email to run the app.
03Where your data lives
Your library is stored at ~/Library/Application Support/Prompto/library.json. This is a plain JSON file you can open in any text editor. Preferences are stored in the standard macOS location under the same Prompto folder.
Both are covered by Apple's file protection and by any full-disk encryption you've enabled (FileVault). If you choose to place your library in iCloud Drive or Dropbox, it is then subject to the privacy and security of that service. Prompto itself still does not transmit it anywhere.
04Network activity
Prompto makes exactly two kinds of network requests, both optional and both initiated by you:
- Update checks. Once a day, if enabled, Prompto asks our server whether a newer version exists. The request contains only the current app version. We do not log IP addresses. You can disable this in Settings.
- License activation. When you enter your license key, Prompto sends it once to our server for verification and receives a signed token in response. No other data is sent.
That's everything. Prompto does not load remote assets, does not download content, does not ping a usage endpoint.
05Payments
Purchases are handled by our payment processor, Paddle, acting as the Merchant of Record. When you buy Prompto, Paddle receives your name, email, billing address, and payment details in order to process the transaction and issue a receipt.
We receive a minimal record from Paddle: your email, the license key issued to you, and the transaction date. We use this to email your license and to help if you request a refund or lose your key. We do not see or store your payment card details at any point.
06Support conversations
If you email support, we store the thread in our helpdesk for as long as needed to resolve your issue. You may ask us to delete it at any time.
If you voluntarily attach diagnostic information — a screenshot, a log file, a copy of your library — please redact anything you consider sensitive first. We will only use what you share to help with your specific issue.
07Analytics & crash reports
Prompto ships with no third-party analytics SDK. There is no Google Analytics, no Mixpanel, no PostHog, no Sentry. Crashes are reported only through Apple's built-in CrashReporter, and only if you have enabled that sharing in your Mac's own privacy settings. We receive these reports anonymously, through Apple, the same way any Mac developer does.
08Children
Prompto is a productivity tool for general audiences and is not directed at children under 13. We do not knowingly collect any information from children.
09Changes to this policy
If we ever change this policy, the new version replaces this one at the same URL and the “Effective” date at the top is updated. Material changes will be announced in the app's release notes and on the Prompto website.
We cannot retroactively change what older versions of the app did; we can only change how future versions behave. The core principle — no collection, no servers, no telemetry — is not something we intend to walk back.
