These terms apply to your purchase and use of Survey Validator (the "Service"). They are written in plain English and intentionally short. Please read them before purchasing.
For $39.99 USD, you receive one PIN granting access to validate one survey through the Service. A "survey" is identified by the content of its question text (a SHA-256 hash of normalized question text). Re-validating, applying AI revisions, and running structural revisions on the same survey are all unlimited and free. Only validation of a meaningfully different set of questions deducts an additional credit (and requires a separate purchase or top-up).
The PIN's one-survey quota is enforced by hash-based deduplication. Unused credits are tied to the PIN and may be refunded within 30 days of purchase if the PIN has not been used for any survey.
The Service analyses your survey across ten independent validation checks (bias, readability, item independence, scale alignment, construct coverage, reliability simulation, inter-rater consensus, and others). It produces a structured score, an AI-revised version of your survey, optional structural revisions you approve item by item, and a Word (.docx) export with a methodology appendix. It does not:
Output should be reviewed by you before deployment. The Service is a tool, not a methodologist of record. Decisions you make from data collected via your survey remain your responsibility.
You agree to use the Service only for:
You agree not to share, resell, or redistribute your PIN. The PIN is for your individual use for the survey it grants access to.
Refunds are issued within 30 days of purchase if the PIN has not been used (no surveys validated). After any survey validation, refunds are not available. Before purchasing, please review the What it catches section, the FAQ, and the privacy statement to confirm the Service fits your needs.
Exception: if a technical fault on our side prevents you from receiving any usable output across all three runs, contact support@validsurvey.app within seven days of purchase and we will issue a full refund or replacement PIN at our discretion.
The full privacy statement is at validsurvey.app/privacy and forms part of these terms. Key points:
The Service produces a reformatted manuscript and a structured copy-editing report — a tool to accelerate your submission, not a substitute for your own review. Review the output before submitting your paper.
Our financial responsibility for any issue with the Service is capped at the $39.99 USD you paid for the PIN. Outcomes downstream of the Service — a journal's editorial decisions, your submission timing, peer-review reception — sit outside that cap.
We aim to keep the Service available but do not guarantee uptime. The Service depends on third-party providers (Anthropic, Posit/shinyapps.io, Cloudflare, Google, Stripe) any of which may experience outages. PINs remain valid for 365 days from purchase. Unused runs after 365 days are forfeited. To extend, pay $39.99 with the same email to add 3 runs and reset the 365-day window from the top-up date.
These terms are governed by the laws of the Province of Ontario, Canada. Disputes will be heard in the courts of Ontario.
