From request to delivery

  1. stage.01

    Request

    Describe the system and the problem in the form below. There is no fee to ask, and asking commits you to nothing.

  2. stage.02

    Scoping call

    An engineer — not a sales script — discusses the system with your team and agrees what an audit or build would need to cover.

  3. stage.03

    Written proposal

    Scope, deliverables, team, schedule and price in writing. Nothing starts and nothing is invoiced before it is signed.

  4. stage.04

    Delivery

    Work in short, reviewable increments, in your repositories and on your infrastructure, with documentation as a deliverable rather than an afterthought.

Privacy notice — how we use what you send

  • Controller. 3S Game Studio OÜ, Poordi tn 3-63, 10156 Tallinn, Kesklinna linnaosa, Harju maakond, Estonia, registry code 16279375. Contact: contact@3sgamestudio.com.
  • What and why. Company name, your name, work email, company size, service area and your description — only to assess and answer your request for a Technical Audit or consultation. Every field is needed for that; nothing is optional and nothing else is collected.
  • Lawful basis. Steps taken at your request before entering into a contract, GDPR Article 6(1)(b). We do not ask for consent, because consent is not the basis for answering you.
  • Retention. Deleted 12 months after we receive it unless it becomes a contract. A scheduled job performs the deletion.
  • Who sees it and where. 3S Game Studio OÜ, and Namecheap, Inc. as the hosting processor. The server is in the United States, outside the European Economic Area; the transfer rests on Standard Contractual Clauses, Article 46(2)(c) GDPR. Not sold, not used for advertising, no automated decision-making.
  • Your rights. Access, rectification, erasure, restriction, portability and objection (Articles 15–21 GDPR). You may complain to the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon).
  • Anti-abuse. A salted one-way hash of your IP address is kept for minutes for rate limiting; the address itself is never stored.

//faq

Questions businesses ask first

>Who does 3S Game Studio OÜ work for?

Companies. We provide IT consulting, custom software engineering and interactive engine programming to businesses under written agreements. We do not provide technical support to consumers.

>What does it cost to request a Technical Audit?

Nothing. Sending the request form is free and creates no obligation. If an audit makes sense, its scope and price are set out in a written proposal before any work starts.

>Does the name “Game Studio” mean you make games for players?

Our engine and simulation practice uses the same techniques that power games — real-time rendering, physics, AI — and some clients are game studios. We sell engineering services to businesses; we do not sell games or in-game items to the public, and we never work on real-money gambling.

>Who owns the code you write?

The client. Intellectual property in bespoke code is assigned to the client under the written agreement, and the code lives in the client’s own repositories from the first commit.

>Do you guarantee an uptime figure?

No figure is published on this site. Availability targets are agreed in writing for each engagement and measured with the client’s own monitoring, because a number we could not show you the measurement for would not be worth printing.

>How can I verify that 3S Game Studio OÜ is a real company?

Registry code 16279375 and EU VAT number EE102395516 are public. The Estonian e-Business Register entry and the European Commission VIES validation service are both linked from the Legal Identity page.
