Editorial policy

Who writes

The Splash team writes and maintains the library. We aren’t clinicians, and no clinician has reviewed the articles yet. Read how we write and check health content for the full process.

Standards

• Every factual claim and every number links to a source, with the date checked.
• We prefer guidelines and systematic reviews, and express uncertainty honestly (“about”, “most”, ranges).
• Every article opens with a quick answer and includes when to see a doctor.
• We write for a reading age of about 9 to 11, and explain medical words.

Use of AI

We sometimes use AI tools to help draft, shorten or simplify text. AI is never the source of a fact. A person checks every fact against the cited source before publishing.

Independence

Splash has no sponsors or affiliate links. No company pays to be mentioned. When we compare Splash with other apps, we date the comparison, link our sources and say where they’re better.

What we won’t claim

• Splash is not contraception and not a medical device. We never say it prevents pregnancy.
• Splash can’t diagnose. We talk about patterns worth mentioning to a doctor.
• Predictions are estimates, shown as ranges. We never quote accuracy percentages.
• We don’t promote diets, “hormone hacks” or unevidenced cycle-syncing promises.

Language

We write in UK English, with US terms noted where helpful. We say “people who have periods” where that’s accurate, and follow the wording of a source when it’s specific. We avoid shame words and never assume a partner’s gender.
