Seamloft Privacy Policy

Last updated: 2026-09-03

No account, no upload: your patterns, projects and stash stay on this phone, and the only things that leave it are the store's purchase receipt and nine counted, anonymous usage events.

Seller: WaveApp LLC

Checkout: Apple · Google

Contact: hello@seamloft.app

Product domain: seamloft.app

1. What never happens

• Seamloft has no account, no sign-in and no server of ours. Nothing you make is uploaded, synced or used to train anything.
• Your pattern files, project names, fabric names, measurements, yardage and cut-piece names have no network path out of the app.
• No AI: nothing is generated and nothing is recognised by a model, on the device or anywhere else.
• No ads, no sale of data.

2. Data we touch

2.1 Data on your device

Data: a local database holding your projects, patterns and their reading positions, cut lists, fit checks, stash fabrics and photos, measurements and settings.

Used to: run the app. It is read by nothing else.

Kept: until you export, delete or uninstall. Export is free and lossless: JSON and CSV, your original pattern files, your fabric photos and a manifest, handed to the share sheet. "Delete everything" clears the device after a confirmation screen.

2.2 Purchase and entitlement

Data: the store receipt and transaction identifiers for the Pro purchase, plus an anonymous app-instance identifier.

Used to: unlock Pro, restore it on a new device, and keep it working offline from a local cache.

Who: Apple App Store or Google Play takes the payment; RevenueCat checks the receipt. We never see your card number.

Basis: performing the purchase contract.

Kept: by the store under its own terms; by RevenueCat while Seamloft is on sale, so Restore purchase keeps working.

2.3 Usage analytics

Data: nine counted events: app open, pattern imported (pdf or image), project created, cutlist created, cutlist piece checked, fit check run (enough or not enough), paywall viewed (which limit), purchase completed, export used. Each carries product, platform and release, and the analytics library attaches the device model, operating system version, locale, time zone, app version and an anonymous device identifier. Never a pattern filename, pattern content, page count, project name, fabric name, measurement, yardage, cut-piece name or free text. Location lookup is off.

Used to: know whether the product works and whether the paywall converts. There is no switch for this; Settings › Privacy shows the same list, and this page is the disclosure.

Who: PostHog, United States.

Basis: our legitimate interest in running the product.

Kept: by PostHog under its terms.

2.4 Support email

Data: what you write to hello@seamloft.app, and your address.

Used to: answer you.

Kept: 12 months after the thread closes.

2.5 The website

seamloft.app uses PostHog for anonymous page analytics: page views, exits, selected buttons, page paths and campaign tags. Its browser identifier lasts 365 days. Events exclude IP address, device details and location, and session recording is off.

3. Processors

• Apple App Store and Google Play — payment and receipts (United States).
• RevenueCat — entitlement verification (United States), under its data processing terms.
• PostHog — app and website analytics (United States).
• Hosting and security providers — site delivery and inbound email routing (United States).

Nobody else receives data from Seamloft. We do not sell data and we show no advertising.

4. Your rights

If you are in the EU, the UK or another place with data-protection rights, you can ask us to show, correct, delete, restrict, export or stop using data about you. You can also complain to your local supervisory authority. Write to hello@seamloft.app; we answer within one month. We hold no record of you beyond a support thread, so most requests end at the export and "Delete everything" controls in the app, or at the store for purchase records.

5. Children

Seamloft is not directed at children, and it collects no personal data from anyone, children included.

6. Changes

If a change would affect what data we touch, we announce it in the app's update notes before it takes effect.
