How we select sources
We prioritize official notices, organizers, major news media, and traceable reference sources. If city-level timing differs, the page explicitly labels scope and links the source.
Editorial Policy
Editorial Policy
How this site selects sources, summarizes information, handles updates, and defines the boundary between information and transactions.
The site confirms date, scope, rules, and sources first, then turns them into pages that are easy to read and easy to check back against source material.
Policy Notes
How this works in practice
How we summarize
We preserve date, place, rule, and usage context first, then rewrite into short paragraphs and lists without turning unverified claims into certainty.
How we handle updates
If a source changes a date, rule, or city rhythm, we update the page and log what changed and why in the Changelog.
How we label uncertainty
When sources differ, we say so directly using language such as 'may' or 'subject to local notice' instead of flattening uncertainty into a false conclusion.
What VoucherData does and does not do
VoucherData provides curated information, rule summaries, and routing links. Checkout, payment, order creation, refunds, and official transaction support remain offsite.
Essentials verification
For Life / Essentials, source tiers are checked on a cadence: utilities weekly, eSIM biweekly, and convenience retail monthly. Price fields use a 'from / at time of review' meaning rather than a live promise.
Reader Promise
Readable first, with sources kept close
Pages are written for people first. Supporting structure still exists underneath, but it should not compete with the main reading experience on the page.
