How our data is gathered

• A source for everything. Each figure comes from a document we link to. Company figures come from the company's own filings or announcements; anything else is attributed to whoever published it.
• A period for everything. Revenue, user and download figures are given with the period they cover and the date they were published.
• Like with like. When we compare companies, we compare the same measure over the same period, and say when a company defines a measure differently.
• Unknown is not zero. A figure we do not have is shown as a dash or "Not disclosed", never as 0 and never as our own estimate.
• Mistakes are corrected openly, under our corrections policy.

The deals tracker records acquisitions, mergers, take-private offers, funding rounds and insolvencies in the dating, matchmaking and social discovery industry. The newsroom adds an entry when it publishes a story about a deal.

Each entry gives the date, the companies involved, the type of deal, its status as of our latest story on it, and its value as disclosed. Where no value was published, it says "Not disclosed". Every entry links to the original announcement or filing and to our story.

Regulation watch records new laws, regulators' decisions, fines, consultations and court rulings that affect dating apps, by country. Entries are written from the regulator's or court's own documents, which each entry links to, and are added as the newsroom reports them.

The stock tracker and the ticker at the top of each page show listed dating companies, including Match Group (MTCH), Bumble (BMBL) and Grindr (GRND). Prices, daily changes, 52-week ranges and market values are fetched every hour on weekdays from Nasdaq's public quote data, with Yahoo Finance as a fallback.

Prices are delayed, not live, and are for information only. If a price cannot be fetched, the last good value is kept and nothing is made up to fill the gap.

Profiles in our company directory, app directory and people pages are written by DII from public sources: the company's own site and filings, regulators' records, app store listings and our own reporting. Each profile links to the stories in which the company or person appears.

Companies can ask us to correct or update a profile by writing to hello@datingindustryinsights.com. A paid listing changes how a profile is presented, not what we say about the company.

Each of our reports lists its sources and explains its method, including any survey, sample or assumption it relies on. When we revise a report, it records what changed and when.

You are welcome to quote figures from DII with a credit to Dating Industry Insights and a link to the page you took them from. Where a figure comes from someone else's document, please cite that too. For larger extracts or a data request, see press or email hello@datingindustryinsights.com.
