About Docka Development OÜ
Last updated:
Docka is built by Docka Development OÜ, an Estonian company (registry code 17579582) based in Tallinn. We build the CRM that crewing agencies run their desk on: the crew roster, the documents, the expiry dates and the sea-service record in the same place. Because a scanned PDF is a claim and not a fact, Docka also checks each certificate against the register of the flag state that issued it.
This page explains who runs Docka, what "primary-source verification" means, how we label each result, and where our checks stop.
Who we are
- Legal entity: Docka Development OÜ
- Estonian registry code: 17579582
- Registered office: Tallinn, Estonia
You can reach us by email through our contact page. The company's legal and registry details are published there in full.
The Docka team
Docka is a small team in Tallinn that has spent its working life around crewing paperwork and the software that handles it. We write the registry connectors ourselves, we read each authority's portal before we wire it, and we review the guides on this site against the primary documents they cite. When a register changes its form or its coverage, the same people who built the connector update the page that describes it; the "Last updated" line on each page is the date that review last happened.
We do not publish individual names on the site. Questions about a page, a connector or a result go to the address on the contact page and reach the person who wrote the code.
What "primary-source verification" means
The primary source for a seafarer certificate is the maritime authority that issued it: for example, Transpordiamet (the Estonian Transport Administration) or the UK Maritime and Coastguard Agency. A certificate is only as trustworthy as that authority's own records.
So instead of reading a document and trusting what it says, Docka goes back to the issuing authority's official register and asks it directly. Where the authority runs a public verification service that answers automatically, Docka connects to that service and reports what it returns. We never re-type the contents of a PDF and call the result "verified".
Two principles hold everywhere in the product:
- We show you exactly how much we could confirm. Every certificate carries a label describing the strength of the check behind it.
- We are honest about our limits. Not every country exposes a live check. Where one doesn't, we say so plainly instead of dressing up a weaker check as a strong one.
Trust levels and registry coverage
Every document in Docka sits at one of four levels, L0 to L3, from a self-uploaded file that nobody has checked to a certificate confirmed against the issuing government's register. L3 is the strongest claim we make, and we only make it when the issuing authority's own register backs it.
The full trust-level table is in how seafarer certificate verification actually works, and the list of every register we check, grouped by what each one lets us do, is on the registry coverage page. Both are generated from the same data the product runs on, so they cannot say more than the code does.
A note on fraud: some websites imitate real maritime authorities. Docka only ever talks to each authority's pinned official domain, and shows a warning for the impostor sites it knows about.
Security and your data
- We never store card or bank details. Payments run through Stripe (card or SEPA). Card and IBAN details go to Stripe; Docka does not keep them.
- Sensitive lookup inputs are pass-through only. Where a check needs a sensitive value (such as a national ID number), it is used for that single lookup and is not stored.
- Seafarers use Docka free. The agency side is a paid subscription; the seafarer side is free.
Pricing, in brief
An agency pays 300 EUR / month plus 2 EUR per billable seafarer per month; seafarers pay nothing; the detail is on the pricing page.
