Deadline guaranteed in the contract
The delivery deadline is a commitment with a contractual penalty — not a marketing promise. Every day of delay on our side = partial refund.

- Cloudflare DNS + CDN
Additional cache layer, DDoS protection and domain management in one panel.
/strony-www/faq // questions and answers
Frequently asked questions.
Will I get access to the source code?
Yes, immediately upon delivery. GitHub repo transferred to your account or our org with full transfer — complete code ownership from day 1, with no retained dependencies.
Can I edit content on my own?
Yes — in the Business and Premium packages we deploy a CMS (typically Decap or Keystatic). You can edit text and images without a developer. Start package: editing via simple Markdown files or optional CMS for an additional fee.
What if I need changes after the site is delivered?
First 30 days of fixes are free. After that — one-time quote or QCare Lite subscription (1 800 zł/mo) with full technical support and SLA.
Can I have a bilingual website?
Yes — i18n is included in the Premium package, available in Business for an additional ~500–800 zł. We use Astro's built-in i18n routing without external plugins.
What guarantees do I have for meeting the deadline?
The contract includes milestones with a specific contractual penalty for delays on our side. The same approach as in QDeployment and QCare — a commitment, not a gentleman's agreement. We are the only provider in this price range on the market that offers this.
