Terms of Service

These terms apply to services provided by Sifartek OÜ (“Sifartek”, “we”) to a business client (“you”). Each engagement also has a signed scope or service agreement. Where that document and these terms differ, the signed document applies. These terms are not aimed at consumers.

Sifartek builds and runs software for businesses: AI systems that work inside a client’s processes, with their output checked by code and by people, and custom software without AI. The services are:

• Mapping and test. A fixed-fee engagement in which we map the process in scope, identify where AI helps, and test it on a sample of your data, with the findings and results returned to you. It is an evaluation, not a deliverable you deploy.
• The pilot. A fixed-price build of one process, defined in a written scope, deployed to an environment you control.
• The monthly service. Hosting support, fixes, model updates and small additions to deployed software, billed monthly.
• Custom software and further builds. Web apps, internal tools, mobile apps and additional processes, scoped and priced separately as fixed-price steps, and, where agreed, an engineer working inside your team on a month-to-month basis under its own service agreement.

Every pilot and further build starts from a written scope that states what the software does, what is out, the acceptance criteria, the delivery date, the price, and what we need from you and by when. You approve it before work starts. Anything outside the scope is quoted separately and only built if you accept the quote. A change you request to the scope may move the delivery date, and we will say so in writing before we accept the change.

• Mapping and test is a fixed fee, stated on the site and in its agreement, payable before work starts. If you proceed to a pilot within ninety days, the fee is deducted from the pilot price.
• A pilot is a fixed price agreed in the scope. Fifty percent is invoiced at signature and fifty percent when the acceptance criteria in the scope are met. No hourly billing.
• The monthly service is a flat fee agreed in writing, invoiced at the start of each month.
• Invoices are payable within fourteen days. Prices exclude VAT. For EU business clients VAT is handled under the reverse-charge mechanism where applicable.
• Late payment may pause work and accrues statutory interest under Estonian law.

If a pilot is not deployed and meeting the acceptance criteria in its scope by the delivery date stated in that scope, you may ask, in writing and within ten working days of that date, for a full refund of the pilot fees you have paid. We will pay it within fourteen days and the engagement ends. This is the remedy for a missed date and is subject to the following:

• It applies to the pilot only, not to mapping and test, the monthly service or further builds, and once per client.
• It requires that you provided the data, access, answers and review time the scope asked for, within the windows it set. Where you did not, the delivery date moves by the same delay and the refund is measured against the moved date.
• A change of scope you requested, and we accepted in writing, moves the delivery date as stated in that acceptance.
• Where a refund is paid, work delivered to that point remains available to you as is, without warranty, and you may keep it. Sifartek keeps no rights over your data.

On full payment you own the code written for you, the configuration, rules and prompts specific to your software, the deployment, and all output it produces. It runs in an account you control. Sifartek keeps its general know-how, and any generic components and tooling that existed before your engagement or were built without reference to your data, and grants you a perpetual licence to use them inside your software. Nothing specific to you is reused for anyone else.

• We sign a confidentiality agreement and a data processing agreement before you send us any data. If your organisation has its own templates, we will work from those.
• Your data is processed on infrastructure hosted in the European Union unless your scope says otherwise, and by the AI model provider named in your data agreement, under that provider’s business terms, which prohibit training on your data. We do not train models on your data either.
• Data shared for mapping and test, and the outputs produced from it, are deleted within thirty days of that engagement ending unless you proceed to a pilot. Pilot data lives in your environment.
• You are responsible for having the right to share the data you send us, and for the lawful use of the output.

Where the software we deliver uses an AI model, the model’s output is checked by code against the rules agreed in the scope, and anything that fails those checks or falls outside them is routed to a person instead of being acted on. The scope names the steps where a person reviews output, and your use of the software assumes those steps are kept. Output from an AI model can still be wrong, and we make no warranty that any output is complete or accurate. We do warrant that the software meets the acceptance criteria in its scope on delivery, and we fix defects against that scope under the monthly service.

To the extent permitted by law, neither party is liable to the other for indirect or consequential loss, including lost profit, lost bids or lost business. Sifartek’s total liability under an engagement is limited to the fees you paid for that engagement in the three months before the event giving rise to the claim. Nothing in these terms limits liability for fraud, or for anything that cannot be limited under Estonian law.

• Mapping and test ends when the findings and results are delivered.
• A pilot ends on acceptance, on a refund under section 5, or by written agreement.
• The monthly service runs month to month. Either party may end it with thirty days written notice. Your software keeps running after it ends; you simply no longer have us maintaining it.
• Either party may end any engagement immediately for a material breach that is not fixed within fourteen days of written notice, or for non-payment.
• Confidentiality and the data terms in section 7 survive the end of an engagement.

These terms are governed by the laws of the Republic of Estonia. Disputes go to Harju County Court in Tallinn. Before that, both parties agree to try to resolve the matter in good faith for thirty days.

We may update these terms. The version that applies to an engagement is the one in force on the date its scope or service agreement was signed. The date at the top of this page shows when it last changed.
