Effective November 1, 2026. This policy explains what personal information we collect when you use our website and app, how we use it, who we share it with, and the choices you have.
Who we are
The ampacity.ai website, the app at app.ampacity.ai, and the public panel sheets the app publishes (together, the "Service") are run by Ampacity.ai ("Ampacity.ai," "we," "us" or "our"). You can reach us at support@ampacity.ai.
What we collect
We collect these categories of personal information:
Account information: your name, email address, the company name and phone number you give us when you start and sign-in details. If you sign in with Google or Microsoft, this includes the name, email address and profile picture that company shares.
Billing information: your plan, your subscription status and your billing history. Stripe collects your credit card details directly. We never see or store your full credit card number.
Content you add: the panel-schedule photos you upload, and the project, panel, circuit and equipment data that you type in or a photo import fills in. This content can include names, addresses and notes you enter.
How you found us: the campaign details described in the next section.
Usage and device information: the IP address, browser and device of each request, which our server logs record and which Clerk records when you sign in. We also count how many photo imports your account has run.
Website visit statistics: the pages visited, the referring website, campaign tags, the browser, operating system and device type, and the approximate location (country, region and city) derived from your IP address. PostHog collects them using the cookie described below.
Product usage and session replays: in the app, the pages you open and what you click, and a replay of each session that we use to fix problems (see "Session replays: how we fix problems" below).
Error reports: when something fails in the app or on our servers, a technical report of the error, the page you were on, and your account ID.
Feedback you send from the app, such as a problem report.
Change history: when someone changes a project or acknowledges a warning on it, the project's history records who did it (their display name), when, and what changed.
Free tries: when you try a panel-schedule import before you have an account, the photo you upload and the schedule we read from it, your email address, your company, your phone number if you give one, the topic you pick under “I’m most interested in” if you pick one, the campaign tags from the link you followed, and a one-way hash of your IP address that we use only to limit how many tries one network can run.
Messages you send us: anything you write to support@ampacity.ai.
Inquiries you send from our website: when you use the form on Talk to us or Engineering, your name, email address, company, role, what you need, your message, the page you sent it from, and the same campaign tags and landing page described in "What sign-up records about how you found us".
What sign-up records about how you found us
Links on our website carry the campaign tags from the link that brought you to us. When you create an account, the app saves any of the following that are present, with the time they were saved, on your account record at Clerk:
The campaign tags utm_source, utm_medium, utm_campaign, utm_content and utm_term.
The ad-click identifiers gclid, gbraid and wbraid (Google), li_fat_id (LinkedIn) and msclkid (Microsoft), if you arrived from one of their ads.
lp: the page on ampacity.ai where you first arrived.
ref: the domain of another website that linked you to us.
Limits on what sign-up records
Each value is cut to 100 characters, except the Google ad-click identifiers (gclid, gbraid and wbraid), which are cut to 512. Nothing else from the link is kept. If none of these values are present, nothing is saved.
The campaign record saved on your account does not use cookies or browser storage and reflects only the visit that led to your sign-up. Separately, PostHog's cookie can connect your earlier website visits to your account.
Session replays: how we fix problems
When something goes wrong in the app, a description rarely tells us enough to fix it. So the app keeps a replay of each session: the screens you saw, where you clicked and what you typed. It is rebuilt from the page, like a screen recording, and it includes what was on screen, such as your projects and panels. Passwords, one-time sign-in codes and card details are never included; card details go into Stripe's secure form, which is not replayed.
We open a replay when you report a problem, when the app records an error in your session, or when we are working out why people get stuck on a screen. We do not use replays to monitor you.
Replays are never sold, never used for advertising, and never shared with anyone except PostHog, the service that stores them for us. They are deleted after 30 days.
How we use it
We use personal information to:
Run the Service: sign you in, read your photos, calculate and store your panels, publish the public sheets you print or share, and bill your subscription.
Support you and keep the Service secure: answer your email, your in-app reports and the inquiries you send from our website, prevent fraud and abuse, and find and fix problems, including by opening session replays and reading error reports.
Understand what works: count visits and trial clicks on our website, see which campaigns and pages lead to new accounts, and see how people use the app.
Improve the Service: improve how we read the panel-schedule images you upload, as described below.
Reach you about your account: a welcome note when you sign up, reminders before your trial ends, billing messages, changes to our terms or this policy, and important notices about the Service.
Tell you about new features: occasional product update emails. Every one has an unsubscribe link, and unsubscribing does not stop the account messages above.
Your images, AI and selling data
We use the images you upload to improve how we extract data from them. That work is tuning how we read images, and nothing more: we don't train AI models, and our AI provider, Anthropic, doesn't train on your data. This work happens inside Ampacity.ai.
We do not share your content with anyone outside Ampacity.ai for their own AI training or for any other purpose of theirs.
To read a photo, we send our AI provider, Anthropic, the image and our instructions for reading it. We don't share facility-identifying details, only the image: we do not send your account details or the facility, project or site information stored in the app. Anything written on the photo itself, such as a building name on the schedule, is part of the image. Anthropic's commercial terms do not allow it to train its models on the photos we send it.
We do not sell your personal information, share it for advertising based on your activity on other websites, or give it to anyone for their own marketing.
Who we share it with
We share personal information only with these service providers, and only as far as each one needs it to run its part of the Service:
Anthropic: reads the panel-schedule photos you upload, so the app can turn them into panel data. It receives the photo only, not your account or facility details.
Clerk: runs sign-in, sessions and account records, including the sign-up details described above, and runs our subscription billing.
Stripe, through Clerk Billing: processes payments and stores your credit card details.
Neon: hosts our database, which holds your account record, your panel data and your uploaded photos, the inquiries you send from our website, and the photos and contact details from free tries.
Railway: hosts the website and the app, and keeps their server logs.
Resend: sends our automatic emails, such as the welcome note, a notice to our team when you sign up or send an inquiry from our website, a note confirming we received your inquiry, and product updates. It receives your name and email address and the message we send, and for the notice to our team about a free import or free try, your company and phone number.
Cloudflare: checks that a free try comes from a person and not a script (Turnstile).
Google Workspace: hosts our email, including support@ampacity.ai and the messages we write to you ourselves.
PostHog: records how our website and app are used, including session replays of the app, error reports and in-app feedback, and stores this in the United States. It also holds the record of first payments that we upload to Google, as described under Google.
Google: the Google Ads tag on our website and app tells Google when a visit from one of our ads reaches sign-up or starts a trial, using Google's advertising cookies. If your account was created on or after October 1, 2026 from one of our ads and your subscription becomes paid, we upload the ad-click identifier and the amount of your first payment to Google, so we can measure which ads bring paying customers.
GitHub: holds our internal bug reports, which may include the text of a problem report you send from the app and your account ID, but not your email address.
Google and Microsoft: if you choose to sign in with one of them, it confirms who you are under its own privacy policy.
Other disclosures
No analytics, advertising or tracking services run on our website or app other than those listed above.
We may also disclose information when the law requires it, to protect the safety and rights of our users or the Service, or to a business that takes over the Service. That business would have to keep following this policy.
Public panel sheets
Every panel and piece of equipment in the Service has a public link, and the QR codes the app prints point to it. Anyone who has the link can read that item's sheet without signing in.
A panel sheet shows the panel's name, location and ratings, its circuit schedule with each circuit's description, and its calculated load, capacity and headroom. An equipment sheet shows the equipment's name, location, ratings and nameplate details, such as manufacturer, model, serial number and year. Sheets do not show your project's name, your notes or tags, or your uploaded photos.
We do not publish a list of these links, and they are hard to guess. But anyone who has a link, or scans a printed code, can pass it on. Do not put personal information in a panel's name, location or circuit descriptions. The app does not currently let you turn a public link off.
Cookies on our website
Our website, ampacity.ai, sets these cookies and browser storage:
PostHog's first-party cookie and browser storage, which hold a random ID so we can recognize a returning visitor and connect a visit to the account you later create. It is shared between ampacity.ai and app.ampacity.ai.
The Google Ads tag sets Google's advertising cookies, which measure whether a visit from one of our ads led to a sign-up or a started trial.
Cookies in the app
The app, app.ampacity.ai, sets these cookies and browser storage. Except for the Google Ads tag, none of them are used for advertising or to follow you across other websites:
The Google Ads tag also runs in the app. It sets Google's advertising cookies and tells Google when a visit from one of our ads leads to a sign-up or a started trial.
Clerk's sign-in cookies, and similar storage in your browser, keep you signed in and protect your account. The app cannot work without them.
sidebar_state remembers whether you left the app's side menu open, for 7 days.
PostHog's cookie and browser storage (the same random ID as on our website, and your session) let us connect your activity, replays and error reports to your account, including your email address so we can find your account when you ask for help.
When you open checkout to enter a credit card, Stripe's payment form sets cookies that help prevent fraud.
Website analytics and your choices
PostHog uses a cookie and connects your website visits to your account once you sign in, so that we can see which pages lead people to the app and how the app is used.
If you would rather not be counted, block JavaScript on ampacity.ai, or use a browser content blocker that blocks analytics. Our website's pages work without JavaScript.
Our website and app do not change how they work when a browser sends a Do Not Track signal.
How long we keep it
We keep your account, your panel data and your uploaded photos, including those from a free try, until you delete them or ask us to delete your account. We keep the email address, company, phone number and topic you give with a free try the same way, until you ask us to delete them. Sign-up campaign details stay on your account record until the account is deleted.
We keep inquiries you send from our website for up to two years, then delete them. Email support@ampacity.ai and we will delete yours sooner.
PostHog keeps session replays for 30 days and usage events for up to 1 year, then deletes them.
When we delete an account, we delete the personal data in it: your account record at Clerk, your name, email address, phone number and company, and your sign-up campaign details. Project data (panels, circuits, equipment, uploaded photos and the public sheets made from them) describes a building, not you. It stays with the project, so its public sheets and QR codes keep working, and a person responsible for the building can take it over later. If you want a project's data removed too, say so in your request and we'll delete it. One exception: a project's change history keeps the display name of whoever made each change or acknowledged each warning, so the record of who did what to a building's electrical system stays complete for its maintenance. It keeps the name only, never your email address, and it is deleted with the project.
Copies in our database provider's backups expire on that provider's schedule. We keep billing records for as long as tax and accounting law requires. Server logs expire on our hosting provider's schedule.
Review, correct, export or delete your data
You can do these things yourself, or by email:
Review and correct: see and edit your projects, panels and equipment in the app at any time. To change your name, email address or sign-in method, open the account menu in the app and choose Manage account.
Download: download any panel's schedule as a PDF from the app.
Export: email support@ampacity.ai from the address on your account to ask for a copy of your data. Within 30 days, we send your project, panel and equipment data in a common file format, together with your uploaded photos.
Delete: email support@ampacity.ai from the address on your account to ask us to delete your account. Within 30 days, we cancel any subscription, delete your personal data, and confirm when that's done. Tell us if you also want your projects' data removed. Otherwise it stays with the projects, as described above.
How we handle your requests
We may ask you to confirm a request from the email address on your account before we act on it. We do not treat you differently for making a request.
If a California privacy law gives you further rights, email us and we will respond as that law requires.
Security
The Service uses encrypted connections (HTTPS). We limit access to your data to what is needed to run and support the Service, and we rely on our providers' security controls. No system is perfectly secure, so we cannot guarantee that your data will never be accessed without permission. If a breach affects your personal information, we will tell you as the law requires.
Children
The Service is for business use by adults. We do not knowingly collect personal information from anyone under 18. If you believe a child has given us personal information, email support@ampacity.ai and we will delete it.
Where your data is stored
Your data is stored and processed in the United States.
Changes to this policy
When we change this policy, we post the new version on this page and update the effective date at the top.
If a change affects how we use or share personal information we already hold, we email the address on your account before the change takes effect.
