A clearer first look.
Practical guidance for capturing a job and reviewing measurements before a quote.
How accurate are the measurements?
±1.5 cm across roughly 2 m is a validation target, not a guarantee for every scan. Capture quality, scale source and marking geometry affect each result. Use the uncertainty shown on the desk and verify final dimensions on site.
What does ±σ mean?
σ describes the estimated uncertainty of a measurement, including marking geometry and the scale source. It is not a guaranteed maximum error. Review flagged results before quoting, and verify on site before ordering.
What makes a good capture?
Follow the capture tutorial: hold the phone steadily, complete the calibration sweep, then move across the job with overlapping views. Keep the full opening visible, use steady lighting and avoid moving objects.
Why can a scan fail?
A capture may not provide enough usable overlapping views or a reliable reconstruction. We do not show a specific cause unless the system supplies one. Ask the customer to repeat the capture with a new link and follow the tutorial.
How long is a link valid?
An unused link expires after seven days. A capture already started follows the existing scan status; the unused-link rule does not expire a completed scan.
Plans, credits and billing
What is a credit, and when is one used or returned?
One credit covers one scan. Creating a scan link holds 1 credit. The credit is used once the result is ready with high or medium confidence; a low-confidence result is not charged. The hold returns if you cancel the unused link, if the customer doesn't capture within 7 days, or if processing fails.
How do monthly credits and extra credits differ?
Your plan adds its monthly credits each paid month, and unused monthly credits end with that month. Extra credits can be bought while a plan is active and stay usable for 12 months, even after the plan ends. A new link always uses the credits that expire first. The free pilot credits last 30 days.
How do I subscribe, change plan or cancel?
Choose a plan in My plan & credits; payment is handled by our payment provider, Lemon Squeezy. To change plan, cancel in Manage subscription and choose the new plan when the current one ends. Cancelling stops the next renewal: your plan and this month's credits stay active until the end of the paid month, and extra credits stay usable until they expire.
What happens to my credits after a refund?
When a payment is refunded, the unused credits from that payment are removed. Credits already used for scans stay used, and other credits are not affected. Contact us if you think a refund is due.
Where are my invoices and receipts? How do I update my card?
Lemon Squeezy e-mails a receipt for each payment. Open Manage subscription in My plan & credits to see invoices and update your card. If a payment fails, update your card there; new monthly credits are added once the payment goes through.
Who do I contact about billing?
Use the contact page or the support details below. Include the e-mail address of your Sightimate account, but never your card details.
