Cookie Policy

We use three categories: strictly necessary (always on), analytics, and marketing & affiliate (both optional). Optional cookies stay off until you allow them. You can change your choice any time on the Cookie Settings page.

• Strictly necessaryAlways on

  Required for the site to function. These are set without asking because the sign-in, checkout, regional pricing, and consent features do not work without them.

• AnalyticsOptional

  Help us understand which calculators and guides are used so we can improve them. Off by default; only on when you allow them. Data is aggregated and anonymized.

• Marketing & affiliateOptional

  Used when you follow a retailer or affiliate link so a referral can be attributed, and to measure campaign performance. Off by default.

The cookie consent record is kept in your browser's local storage rather than a cookie file; it is covered here because it serves the same purpose.

When you allow a category, the cookies listed above are set or read by these third parties on behalf of Aperture Forge LLC. Each processor is governed by its own privacy policy, linked where available.

• Paddle.com — Merchant of Record for checkout. Sets strictly necessary cookies to keep your purchase secure. See the Paddle Privacy Policy.
• Google Analytics 4 (Google LLC) — anonymized, aggregated usage analytics. Only active if you allow analytics cookies. See Google's Privacy Policy.
• Retailer & affiliate networks — when you click a retailer or affiliate link, those sites may set their own marketing cookies to attribute the referral. Those cookies are governed by the retailer's own privacy policy, not this one.

You can accept or reject optional cookies from the consent banner, or any time on the Cookie Settings page. Rejecting optional cookies does not affect your ability to use the calculators or the site.

Your browser also lets you block or delete cookies in its settings. Blocking strictly necessary cookies will sign you out and may prevent checkout and regional pricing from working.

No. We do not set advertising tracking cookies that follow you across other sites. Marketing cookies here are limited to attributing a referral when you actively follow a retailer or affiliate link from our site.

If we add, remove, or change a cookie or processor we will update this page. Where a change introduces a new non-essential cookie we will ask for your consent again.
