Hidden Fee Database: 2026 Evidence Review
A transparent machine-readable database of 25 verified public-source records about fees, billing, contracts, renewals, and unexpected charges.
Current status: The public database contains 25 verified public-source records. Each record links to its original source and retains the evidence context, collection date, classification, and limitations needed for responsible citation.
Research record
Who: DetectHiddenFees Research Lab.
What: A verified public-source review of fee terminology, contract clauses, cancellation terms, renewal language, and unexpected charges; this is a documented sample, not a representative prevalence study.
When: The 25 sources were collected and reviewed on August 8, 2026. The public manifest was last updated August 8, 2026.
How: A record must retain its source URL, scope, evidence reference, classification, and verification status before it can support a finding.
Data size: The published sample contains 25 verified records. Its category counts describe this sample only; no market-wide prevalence statistic is calculated.
Limitations: A category or example does not establish that a fee is common, unlawful, deceptive, or representative. Inspect the manifest and methodology before citing the status.
Sample, not market index
The records document what authoritative public sources say about fees, billing, contracts, renewals, and consumer-protection context. Counts are descriptive of this reviewed sample; they are not estimates of how often companies charge a fee.

Evidence summary
FACT: The release contains 25 individually reviewed records drawn from live public FTC, CFPB, CMS, and other authoritative government sources. Every public record retains a canonical source URL, evidence reference, collection date, classification, and limitation.
CALCULATION: The dataset contains 25 verified records. The public JSON manifest reports one sample count for each of 25 fee or clause categories because the current review is organized around distinct source-level examples.
OBSERVATION: The reviewed sample spans mandatory fee disclosures, consumer-finance and payment fees, medical billing and financing, automotive add-ons and transaction charges, subscriptions, home-improvement guidance, and consumer billing disputes.
INTERPRETATION: The sources are useful for definitions, warning signs, disclosure context, and document-review questions. They do not establish how common a fee is across a market or whether a particular charge is unlawful in every jurisdiction.
LIMITATION: This is a curated evidence review of public guidance, not a representative survey, enforcement census, pricing panel, or estimate of consumer harm. No prevalence, average amount, accuracy, savings, or market-wide percentage is published.

Record structure
Each record identifies its source, organization, document type, industry, collection date, fee wording, category, amount when stated, recurrence, clause, cancellation or renewal terms, evidence reference, and verification status.
What a database entry will not mean
A listed fee will not automatically be unlawful, unreasonable, hidden, negotiable, or representative of an industry. Those descriptions require separate evidence and appropriate jurisdictional context.
Privacy and rights
The public dataset does not contain personal information, customer-uploaded documents, confidential contract text, or material without a publication basis. The research team will retain source and correction notes for published records.
