Snapchat

visual messaging and stories · live · since Sep 2011

People send disappearing photo and video messages and chats to friends, post Stories, and watch creator and publisher videos in Spotlight and Discover.

How it is run

nine questions
ArchitectureWho holds your account and posts?

One company

open protocol: no

move your account and keep your followers: no

hub: Snap Inc.

Snaps, chats and Stories live only on Snap's own servers, and the terms forbid unauthorised third-party apps or building apps that touch the service without Snap's written consent. No account can be moved with its friends to another provider; a data download does not count here.

Business modelWho pays, and for what?

Targeted ads · subscriptions

Advertising was 87% of Snap's $5.93bn revenue in 2025 (96% in 2023). 'Other revenue' ($745m) is mainly subscriptions (Snapchat+, Lens+, the ad-free Snapchat Platinum, Memories storage), plus a fee from an unnamed 'AI platform partner' and hardware sales Snap calls not material. Ads are personalised on interests, activity and data from partners and advertisers, except for EU accounts of 13–17-year-olds.

OrganisationWhat kind of organisation runs it?

Listed company

control: Snap Inc. (NYSE; the listed Class A shares carry no votes); co-founders Evan Spiegel and Robert Murphy hold over 99% of the votes, Spiegel alone a majority

Class C shares carry ten votes each, Class B one, Class A none; the co-founders' Class C shares give them their control (the 10-K lists two holders of record of Class C, which we read as the co-founders). The 10-K says Spiegel alone may exercise voting control, including over a merger or sale of the company. Snap files no proxy statement because its listed shares have no vote, so the 10-K is the source.

FeedWho decides what you see?

Ranked, with a non-profiled option

Snapchat opens on the camera; chats are not a feed. Its public content feeds, Spotlight and Discover in the Stories tab, are personalised and ranked by Snap's algorithms. Users in the EEA, the UK and Switzerland can switch personalisation off in Settings, after which content is recommended only on language, age and country.

ModerationWho moderates?

The operator

Snap reviews, restricts and removes content and accounts under its Community Guidelines, and says it does not review all content. The terms give users no moderation role beyond reporting and appeals.

AI trainingDoes your content train AI?

Trains its own AI, with an opt-out

a setting or form to opt out: yes

Snap may use publicly posted content (Spotlight, Public Stories, Snap Map) to train its own generative AI content-creation models, and uses My AI conversations to improve My AI. Users can opt out of the public-content use in Settings, though opting out does not undo past training. Snap's terms, privacy policy and help pages do not say it licenses user content to third parties for AI training.

SizeHow big is it?

95.9M a month in the EU

counted: average monthly active recipients in the EU, as the DSA requires them

period: Jan–Jun 2026

Average monthly active recipients in the EU under DSA Art. 24(2), from the total row of Snap's H1 2026 DSA transparency report (published 31 August 2026). France (28.8m) and Germany (19.5m) are the largest countries.

What each layer rests on

checked 25 Sep 2026
07OperatorWho serves the app?

Snap Group Limited · United Kingdom

London, Companies House 09763672. It provides Snapchat outside the US and Asia-Pacific, so EU users contract with a British company. Snap B.V. in Amsterdam is only Snap's legal representative under the GDPR and the DSA. Designated a very large online platform on 25 April 2023; 95.9 million average monthly active recipients in the EU, January to June 2026.

07OwnerWho owns the operator, where someone else does?

Snap Inc. · United States

A Delaware corporation, listed on the NYSE, whose two co-founders hold over 99% of the votes. Snap Group Limited is held through two further UK holding companies.

07ProtocolWho writes the rules of the network?

Snap Inc. · United States

protocol: proprietary

A closed client-server service; the terms forbid unauthorised third-party apps.

07Shared servicesWhat does it lean on but not run?

None

07CodeWho builds the software?

Snap Inc. · United States

licence: proprietary

Built by Snap Inc., with smaller engineering teams in Vienna, Paris and Eindhoven, mostly on lenses, hardware and chips.

07VerificationWho checks users' identity, age or account?

k-ID (Kidentify Pte. Ltd.) · Singapore

checks: age

ID needed to post: no

Age is self-declared at sign-up. k-ID checks age only when Snapchat asks, for example for accounts locked as underage. The Commission opened proceedings in March 2026, suspecting self-declaration is not enough.

06ModelsWhose models moderate, rank or check?

OpenAI · United States

also Google · United States: Gemini models behind My AI, and CSAM-detection tools

My AI runs on third-party language models, and its chats may be used to improve Snap's products and personalise ads. Moderation also uses Microsoft's PhotoDNA and Snap's own models.

05DataWhere does the data sit?

Snap Inc. · United States

where: The United States and other countries outside the user's own, with no EU storage commitment. The controller for EU users is the US parent itself, so Snap has no lead supervisory authority in the EU.

transfers: To the US under standard contractual clauses or the Data Privacy Framework, which Snap Inc. has joined. As a US company Snap answers US legal process; EU authorities must go through mutual legal assistance.

04ServersWho runs the servers?

Google Cloud · United States

also Amazon Web Services · United States: the other of Snap's two clouds, with an API gateway in eu-west-1 (Ireland)

region: API gateways in AWS eu-west-1 and on Google Cloud; storage regions not disclosed

Snap runs almost entirely on Google Cloud and AWS. The EU-named gateways put front-door computing in Ireland; they are not evidence of EU storage.

where a claim in circulation is wrong

  • Snap B.V. in Amsterdam provides Snapchat in the EU, as the Commission's list of very large platforms suggests.

    EU users contract with Snap Group Limited in the UK, and the controller of their data is Snap Inc. in the US. Snap B.V. is only Snap's legal representative, and the Commission's own designation decision records that neither company has an establishment in the Union.
