Booking engine

1. 01Each tour declares what it claims, a jeep and a guide, and for how long including the drive back
2. 02Postgres refuses overlaps with an exclusion constraint, so a double booking is impossible even when two people try at once
3. 03A slot is held for fifteen minutes while the guest pays, and released automatically if no payment arrives
4. 04Online booking closes 48 hours before departure, where the right to a refund ends
5. 05Seasons and weekdays per tour, closed days set in the admin calendar
6. 06The calendar opens on the first month with a free day, so a guest never lands on an empty month
7. 07The terms version a guest accepted is stored with every booking

Payments

1. 01Teya's card form sits inside the booking page, card numbers never pass through our servers
2. 02Teya's webhooks are verified by public-key signature before anything is recorded
3. 03A regular sweep asks Teya about open payments, so a confirmation arrives even when a webhook is lost
4. 04A payment link for phone bookings: one click in the admin, the guest pays by card on a page of their own
5. 05The link carries a secret token, stored only as a SHA-256 hash
6. 06A double payment, a wrong amount or a payment after a cancellation is recorded as a refund owed, never kept
7. 07Magnús makes refunds himself in Teya and marks them done in the admin

Admin

1. 01Everything in Icelandic, with a help page that walks through every task step by step
2. 02An overview of upcoming tours, outstanding payments and the last 30 days of sales
3. 03Record a phone booking: the slot is claimed at once, paid or unpaid
4. 04A cancel form that works out the refund from when the cancellation arrived, by email or phone
5. 05A tour editor in both languages: price, length, group size, season and photos
6. 06FAQ, page text and the wording of every email in English and Icelandic
7. 07A sales report by month and tour, downloadable as CSV
8. 08A search-engine page that sends every page to Bing and others through IndexNow at once

Email

1. 01A confirmation with the terms attached and a calendar file for the tour
2. 02A reminder the evening before: the time, the pickup, what to wear and what happens if the weather turns
3. 03One request for a Tripadvisor review the day after, which the guest can decline
4. 04Mail to Magnús for every booking, payment and refund that needs doing
5. 05Supabase's sign-in mail goes through the same template via the Send Email hook, all from mudshark.is

Privacy & security

1. 01RLS on every table: the public reads published tours only and can never read a booking
2. 02Guests' phone, pickup and notes are deleted 90 days after the tour, names and payments kept for bookkeeping
3. 03Abandoned checkouts are deleted automatically when no money moved
4. 04Cookie consent by category, each choice recorded as proof, Google and Meta tags only after consent
5. 05First-party analytics without cookies or IP addresses
6. 06A nonce-based CSP in the admin, rate limits on forms and sign-in
7. 07Terms, privacy policy and accessibility statement in both languages

Search & AI agents

1. 0136 old Weebly URLs land on the right pages in one hop, whatever their case
2. 02Structured data: a travel agency, a guide with a PhD, tours with prices, and FAQ
3. 03Sitemap and hreflang for English and Icelandic, an OG image for every page
4. 04An MCP server AI agents talk to when looking for tours and free dates
5. 05WebMCP in the browser, and llms.txt describing the site to language models
6. 06Lighthouse's agentic-browsing check runs on every change
