FAQ

Common questions.

Does Pro cover all tools — including future ones?+
Yes. One Pro subscription gives you unlimited access to every tool currently in the catalog and every tool we ship after you subscribe. No add-ons, no separate charges.
What is the $49/year deal?+
If you pay annually you get 12 months for $49 — that's $4.08/month instead of $7. You save $35 compared to paying month-by-month.
Can I cancel Pro at any time?+
Yes. Cancel from your account dashboard at any time. You keep Pro access until the end of your billing period. No cancellation fees.
What counts as a "use" in the Free plan?+
Each time you run a tool calculation or operation, it counts as one use. The counter resets every 24 hours at midnight UTC. Three uses per day is per tool — not a shared pool across all tools.
Do you offer refunds?+
If you are unhappy within the first 7 days of a new Pro subscription, email hello@dlockerlabs.com and we will refund you — no questions asked.
