Privacy Policy

Effective date: October 26, 2026

Hardcastle Home Services LLC (“we,” “our,” “the app”) operates Prominent, a home maintenance tracking tool. This policy explains what information we collect when you use it, how it's used, and the choices you have.

What we collect

  • Account info: your name, email address, an optional profile photo, and a securely hashed password (we never store your password in plain text, and we never see it in a form we could read).
  • Home and equipment details: whatever you choose to enter — addresses, equipment makes/models/serial numbers, purchase dates and costs, maintenance history (including any cost, contractor, and notes you record when you complete a task), projects, contractors, and notes.
  • Uploaded files: photos, manuals, receipts, warranties, and other documents you attach to a home, room, piece of equipment, task, or project, photos you add when you complete maintenance, and photos you send in an AI conversation.
  • AI-assisted content: if you use data-plate scanning, parts lookup, maintenance plans, inspection report import, or the Ask Prominent chat, the photo, document, or text you submit is sent to our AI provider (Anthropic) to generate a response. Ask Prominent conversations are saved to your account so you can come back to them. See “Third parties” below.
  • Payment details: handled entirely by Stripe, on Stripe's own checkout page. We never see or store your card number. We keep only a reference to your Stripe customer and subscription, your subscription status, and your trial and renewal dates.
  • Your answers at the start: if you answer the questions at prominentos.com/start before creating an account, your answers stay in your browser and are only sent to us when you create your account.
  • Usage records: counts of how often you've used each AI feature, used to enforce fair-use limits; a log of each AI request (which feature, whether it worked, what it cost us, and the make and model number of the equipment involved); and a record of which reminder emails we've sent you, so you aren't sent the same one twice. To block abuse, we also keep short-lived records of sign-in, signup, and password-reset attempts, tied to the email address or IP address used; these are deleted within a few days.
  • Page-visit analytics: we use Vercel Analytics to count page visits. It records the page visited, the site you came from, your browser, device type, and country. It doesn't use cookies and can't follow you from one day to the next. We don't run advertising or ad-tracking scripts.

How we use it

Solely to operate the app for you: storing your home records, generating your maintenance schedule, sending you reminder emails (which you can turn off in Settings), sending account emails such as your welcome and trial emails and password resets, managing your subscription, and powering the AI features you choose to use. We do not sell your data, and we do not use it for advertising.

Third parties we rely on

To actually run the app, a few specific services process your data on our behalf, each only for its part of the service:

  • Anthropic — processes the photos, documents, and text you submit to AI features.
  • Stripe — processes payments and stores your payment details.
  • Resend — delivers the emails the app sends: reminders, weekly summaries, warranty notices, account and trial emails, password resets, and messages you send us through the in-app feedback form.
  • ImprovMX — forwards email sent to support@prominentos.com to our inbox.
  • Vercel — hosts the application and your uploaded files, and provides the page-visit analytics described above.
  • Neon — hosts the database where your records are stored.
  • Sentry — receives a technical report when something in the app breaks, so we can fix it. These reports describe the error and the page or request involved. We don't deliberately include your name, email address, or records, though an error message can occasionally contain a piece of the data that caused it.

Each of these processes your data under its own terms and privacy policy.

Sharing your home with others

If you create a share link (for a house-sitter, renter, or a property listing), anyone with that link can view the specific information that link is scoped to show — never your full account or other homes. You can revoke any share link at any time from that home's page.

If you share a home's reminders with someone (a spouse or partner, for example), we store the name and email address you give us for them, send them one email asking whether they want the reminders, and send reminders only if they say yes. They see the task names, due dates, and the home's name in those emails, and can mark a task done or move it; they can't see anything else in your account. Every email lets them stop, and you can remove them at any time from the home's Share window, which deletes their details.

Cookies and browser storage

We use four cookies, none of them for tracking or advertising: one keeps you signed in, two protect the sign-in process (one guards against forged requests, the other remembers which page to return you to after signing in), and one remembers which of your homes you last selected. Stripe's checkout page is on Stripe's own site and sets its own cookies under Stripe's privacy policy.

The app also saves a few things in your browser's own storage, on your device: your light or dark theme, unsaved form drafts, your answers at the start until you create your account, which notifications you've read or dismissed, whether you've seen the welcome screen or hidden the setup checklist, and when you were last active, so you can be signed out after a period of inactivity.

Data retention and deletion

Your data is retained for as long as your account is active. Deleting a home moves it to Recently Deleted, where you can restore it for 30 days; after that, it and everything under it (rooms, equipment, tasks, documents, projects, and uploaded files) is permanently removed. You can also delete a home permanently right away from Recently Deleted.

You can permanently delete your entire account at any time from Profile → Danger Zone, or by emailing us at support@prominentos.com if you'd rather we do it for you. This cancels any subscription and removes your account, your homes (including any in Recently Deleted), and all of your uploaded files. Our log of AI requests keeps its cost figures for our own accounting, with your account removed from it. Stripe keeps its own records of past payments, under its own privacy policy.

So that we can recover from an accident, we keep backups: the database can be restored to any point in the past 7 days, and uploaded files are copied each night to a separate private backup. Anything you delete, including a whole home or your account, can remain in those backups for up to 30 days before it is gone for good.

You can download a copy of your records (homes, rooms, equipment, tasks, documents, projects, and contractors) at any time from Profile → Account Information → Export.

Security

We use industry-standard practices to protect your data in transit and at rest, including encrypted database connections, hashed passwords, and access controls so that, inside the app, your records are visible only to you (and to anyone you've explicitly shared a link with). Our admin tools show account-level details only — name, email, plan, number of homes, and when the account was last used — not your home records.

Changes to this policy

We may update this policy from time to time. We'll update the effective date at the top of this page when that happens.
