Frequently asked questions

Can I cancel anytime?
Yes — click Manage subscription and choose Cancel. You keep access until the end of the current billing period, then revert to Free. No cancellation fees, no hoops.
Do you offer refunds?
We don't have a fixed refund window — cancel anytime and you won't be charged again. If you canceled and still got charged (e.g. forgot to cancel before renewal), email [email protected] and we'll sort it out.
Will my limits reset instantly if I upgrade mid-day?
Yes. As soon as Stripe confirms payment, your quota jumps from 5/day to 50/day (Pro) or unlimited (Premium) on the next request — no logout, no page reload needed.
What counts as a "run"?
A run is a single press of the main action button on a capped tool — Calculate, Convert, Generate, Analyze, and the like. Opening the page, scrolling the results, and tweaking the inputs all cost nothing. On Pro, 50 runs per tool per day is more than most power users ever touch; on Premium, there's no counter at all.
Which tools have a daily cap?
The tools that carry real work forward — pro-grade finance, investment, trading, crypto, real-estate, and tax calculators; SEO, webmaster and server utilities; developer hashes and text pipelines; AI-powered generators. In short: the tools you'd open on the clock. Pro raises every one of them to 50 runs a day; Premium removes the cap entirely. Pro pays for itself the first time it replaces a trip to a paid competitor or a stalled spreadsheet.
Can I switch between Pro and Premium, or monthly ↔ annual?
Yes. Open Manage subscription from this page (after signing in). Stripe pro-rates unused time automatically, so you only pay the difference.
What does "My Toolbox" do, and how does it change across plans?
My Toolbox is the panel on the right edge of every page that keeps your favourite tools one click away.
  • Free — save up to 3 tools, Manual Mode only.
  • Pro and Premiumunlimited saves, plus Automatic Mode: every tool you use is silently remembered and queued for you, so next time it's already there waiting.
If you bounce between half a dozen calculators a week, Automatic Mode alone can save more time than the subscription costs.
No account? How does the site know I'm a subscriber?
We deliberately don't make you create an account — no password to remember, no marketing emails, ever. After checkout, Stripe hands us back an encrypted membership cookie that unlocks every page on this browser. The cookie doesn't expire unless you clear it or cancel. Switching to a new browser, phone, or laptop? Open Access Premium, type the email you paid with, and we'll email you a one-time link that restores access on that device. Your billing history lives with Stripe under that same email.
Can I use my subscription on more than one device?
Yes — there's no device limit, as long as it's you using them. Activate on your home laptop, work PC, phone, tablet — every device you personally own or control. Open Access Premium on each new browser, type the email you paid with, and we'll email a one-click link that unlocks that device.

One caveat — this is a personal subscription. Please don't forward your Access Premium link, hand out the membership cookie, or share the account with friends, colleagues, or across a household. We do monitor for telltale patterns of account sharing (widely separated simultaneous sessions, bulk link forwarding) and may rate-limit, suspend or terminate access without refund — see the Personal Use clause in our Terms. Need coverage for a team? Drop us a line and we'll set something up.
I'm a long-time subscriber — does anything change?
No. Your existing plan stays active with full Premium (unlimited) access at whatever rate you originally signed up for. If you ever lose access after clearing cookies, use Access Premium to restore with the same email address.
Is my payment information safe?
All card data is handled by Stripe, which is PCI-DSS Level 1 certified. We never see or store card numbers. Your receipts and billing history live in the Stripe Customer Portal.
