+# Privacy Policy — trails.cool
+
+Datenschutzerklärung / Privacy Policy
+
+Stand / Last updated: 2026-04-20. Die deutsche Fassung ist maßgeblich.
+The German version is authoritative; English summaries follow each
+section.
+
+1. Verantwortlicher
+
+Verantwortlich für die Datenverarbeitung im Sinne der DSGVO ist:
+
+Ullrich Schäfer
+
+Mehringdamm 87
+
+10965 Berlin
+
+Germany
+
+E-Mail:
+
+legal@trails.cool
+
+English.
+Data controller under GDPR is the party named
+above. Contact for any data-protection matter: legal@trails.cool.
+
+2. Erhobene Daten und Zwecke
+
+Wir verarbeiten nur die Daten, die für den Betrieb der jeweiligen
+Funktion erforderlich sind. trails.cool besteht aus zwei Teilen:
+dem
+Journal
+(trails.cool, mit Konto) und dem
+
+Planner
+(planner.trails.cool, anonym).
+
+Kontodaten (Journal):
+E-Mail-Adresse,
+Benutzername, Anzeigename, Passkey-Public-Key. Zweck:
+Kontoverwaltung und Anmeldung.
+
+Nutzerinhalte (Journal):
+Routen (GPX-Daten,
+Geometrie, Titel, Beschreibung) und Aktivitäten (Titel,
+Beschreibung, Datum, Verknüpfung zu Routen). Zweck: Speicherung
+und Anzeige innerhalb des Dienstes. Jede Route und jede
+Aktivität hat eine Sichtbarkeits-Einstellung
+(
+privat
+/
+nicht gelistet
+/
+öffentlich
+),
+die standardmäßig auf
+privat
+gesetzt ist. Inhalte,
+die Sie ausdrücklich auf
+öffentlich
+setzen, sind
+weltweit abrufbar – einschließlich auf Ihrem öffentlichen
+Profil unter
+/users/<benutzername>
+– und
+können von Suchmaschinen indexiert werden.
+
+Anmeldedaten (Journal):
+kurzlebige Magic-Link-Token
+(zur E-Mail-basierten Anmeldung). Zweck: Authentifizierung.
+
+Sitzungscookie (Journal):
+eine zufällige
+Sitzungs-ID nach dem Einloggen. Zweck: Authentifizierung während
+der Sitzung.
+
+Planner-Sitzungsdaten:
+anonyme Sitzungs-ID,
+kollaborativer Zustand (Wegpunkte, Notizen). Keine Zuordnung zu
+einer Person. Zweck: gemeinsames Planen von Routen.
+
+Server-Logfiles:
+IP-Adresse, Zeitstempel,
+HTTP-Methode, Pfad, Statuscode, User-Agent. Zweck: Sicherheit,
+Betrieb, Fehlersuche. Details siehe Abschnitt 4.
+
+Fehlerdaten (Sentry):
+Stacktraces,
+Fehlermeldungen, Browser-/OS-Information aus dem User-Agent,
+Performance-Metriken. Bei eingeloggten Journal-Nutzer:innen
+zusätzlich die Nutzer-ID (keine E-Mail, kein Benutzername).
+IP-Adressen werden nicht aktiv gespeichert, ebenso keine Cookies
+und keine Formulareingaben.
+
+English.
+The Journal stores only what you provide (account
+details and your own routes/activities) plus short-lived auth
+artefacts. Each route and activity has a visibility setting
+(
+private
+/
+unlisted
+/
+public
+)
+that defaults to
+private
+; content you mark
+
+public
+is world-visible (on your public profile and
+indexable by search engines). The Planner is anonymous and holds
+only ephemeral session state. Server logs and Sentry error data
+are covered separately below.
+
+3. Rechtsgrundlagen
+
+Art. 6 Abs. 1 lit. b DSGVO (Vertragserfüllung):
+
+Kontoführung, Anmeldung per Passkey oder Magic Link, Speicherung
+und Anzeige der von Ihnen erstellten Routen und Aktivitäten,
+Versand notwendiger Transaktions-E-Mails, Bereitstellung anonymer
+Planner-Sitzungen. Ein Konto sowie die Bestätigung der
+Nutzungsbedingungen sind Bestandteil dieses Nutzungsvertrags –
+sie sind
+keine
+Einwilligung im Sinne von Art. 6 Abs. 1
+lit. a DSGVO.
+
+Art. 6 Abs. 1 lit. f DSGVO (berechtigte Interessen):
+
+kurzzeitige Server-Logfiles zur Sicherung des Betriebs und zur
+Missbrauchsabwehr, Rate-Limiting, Fehlermonitoring über Sentry
+zur Sicherstellung der Funktionsfähigkeit des Dienstes.
+
+English.
+Contract (Art. 6(1)(b)) covers everything
+account- and content-related; legitimate interests (Art. 6(1)(f))
+cover short-lived server logs, rate-limiting, and error monitoring.
+We do
+not
+rely on consent for any of this.
+
+4. Server-Logfiles
+
+Beim Aufruf der Dienste werden automatisch technische Informationen
+protokolliert:
+
+IP-Adresse
+
+Zeitstempel
+
+HTTP-Methode, Pfad, Statuscode
+
+User-Agent (Browser, Betriebssystem)
+
+Zweck:
+Sicherheit, Betrieb und Fehlersuche.
+
+Rechtsgrundlage:
+Art. 6 Abs. 1 lit. f DSGVO.
+
+Speicherdauer:
+maximal 14 Tage, danach automatische
+Löschung. Eine Zusammenführung dieser Daten mit anderen Datenquellen
+findet nicht statt.
+
+English.
+HTTP requests to our servers are logged (IP,
+timestamp, method, path, status, user-agent) for up to 14 days for
+operational and security purposes under Art. 6(1)(f), then deleted.
+
+5. Speicherdauer
+
+Konto und zugehörige Inhalte: bis zur Löschung durch Sie
+
+Planner-Sitzungen: automatische Löschung nach 7 Tagen Inaktivität
+
+Magic-Link-Token: 15 Minuten
+
+Server-Logfiles: maximal 14 Tage
+
+Fehlerdaten (Sentry): 90 Tage
+
+Hinweis Alpha: Während der Alpha-Phase behält sich der Betreiber
+ausdrücklich vor, die Datenbank zurückzusetzen oder einzelne
+Datensätze zu löschen. Dies kann zu Datenverlust führen, bevor Sie
+eine Löschung veranlassen. Details dazu in den Nutzungsbedingungen.
+
+English.
+Account and content kept until you delete them.
+Ephemeral data (sessions, magic-link tokens, logs, Sentry events)
+deleted automatically on the schedules above. Alpha caveat: the
+operator may reset the database or delete individual records
+during alpha, which can cause data loss before you request
+deletion. See the Terms of Service.
+
+6. Empfänger und Drittanbieter
+
+Wir geben personenbezogene Daten nur an die unten genannten
+Auftragsverarbeiter und Dritten weiter, und auch dort nur im
+jeweils notwendigen Umfang.
+
+Sentry
+(Functional Software Inc.) – Fehler- und
+Performance-Monitoring. Was übermittelt wird: Stacktraces,
+Fehlertext, Browser-/OS-Informationen aus dem User-Agent,
+Performance-Daten; bei eingeloggten Journal-Nutzer:innen
+zusätzlich die Nutzer-ID. IP-Adressen werden nicht aktiv
+gespeichert (
+sendDefaultPii
+ist deaktiviert), ebenso
+keine Cookies und keine vollständigen HTTP-Header. Keine
+Session-Replays. Sentry agiert als externer Dienstleister
+(Auftragsverarbeiter) für die Fehlerbehandlung. Da Sentry ein
+Anbieter mit Sitz in den USA ist, kann im Einzelfall eine
+Übermittlung personenbezogener Daten in ein Drittland im Sinne
+der Art. 44 ff. DSGVO stattfinden; wir stützen uns hierbei auf
+die von Sentry bereitgestellten
+Standardvertragsklauseln.
+
+OpenStreetMap
+– Kartenkacheln werden beim Anzeigen
+der Karten direkt vom Browser von OSM-Tile-Servern geladen. Dabei
+werden
+IP-Adresse und User-Agent
+an OSM übertragen.
+Dies ist notwendig, um überhaupt eine Karte darzustellen; es gilt
+die
+
+OSM Foundation Privacy Policy
+
+.
+
+Overpass API
+(POI-Daten) – POI-Abfragen laufen
+serverseitig über unsere eigene Route
+/api/overpass
+.
+Der Upstream-Dienst sieht nur unsere Server-IP, nicht die Ihrer
+Nutzer:innen. Aktueller Upstream:
+overpass.private.coffee
+
+, der ohne Query-Logs arbeitet. Eine selbst gehostete Instanz ist
+geplant.
+
+BRouter
+– Routenberechnung läuft auf einer von uns
+selbst gehosteten Instanz. Keine Weitergabe an Dritte.
+
+E-Mail-Versand
+– Transaktions-E-Mails (Magic
+Link, Willkommensnachricht) werden über einen konfigurierten
+externen SMTP-Dienst versendet. Dabei wird die E-Mail-Adresse
+der Empfänger:in an diesen Dienst übergeben. Selbst-betriebene
+Instanzen konfigurieren ihren eigenen Mailserver.
+
+Hosting
+– Die Dienste werden in Rechenzentren
+innerhalb der EU betrieben. Ein Auftragsverarbeitungsvertrag mit
+dem Hoster besteht.
+
+English.
+Third parties and what they receive: Sentry (error
+details, no IPs/cookies); OpenStreetMap tile servers
+(your IP and user-agent, directly from your browser, to load map
+tiles); Overpass (via our server-side proxy, so upstream only sees
+our server); BRouter (self-hosted, no third party involved); SMTP
+provider (your email address for magic link / welcome mail);
+hosting provider in the EU under a DPA.
+
+7. Ihre Rechte
+
+Als betroffene Person stehen Ihnen die folgenden Rechte zu:
+
+Auskunft (Art. 15 DSGVO)
+
+Berichtigung (Art. 16 DSGVO)
+
+Löschung (Art. 17 DSGVO)
+
+Einschränkung der Verarbeitung (Art. 18 DSGVO)
+

 ## 1. Schema
 
-- [ ] 1.1 Add `visibility text NOT NULL DEFAULT 'private'` to `journal.routes` in `packages/db/src/schema/journal.ts`

-- [ ] 1.3 Export a shared type `type Visibility = 'private' | 'unlisted' | 'public'` from `packages/db/src/schema/journal.ts` (or a small adjacent module) and reuse at the app layer
+- [x] 1.1 Add `visibility text NOT NULL DEFAULT 'private'` to `journal.routes` in `packages/db/src/schema/journal.ts`

+- [x] 1.3 Export a shared type `type Visibility = 'private' | 'unlisted' | 'public'` from `packages/db/src/schema/journal.ts` (or a small adjacent module) and reuse at the app layer
 
 ## 2. Server-side access helper
 
-- [ ] 2.1 Add `canView(content, user)` in `apps/journal/app/lib/auth.server.ts` that returns `true` for `public`, `true` for `unlisted` (the direct-URL case — callers pass `true` when routed to a detail page, `false` when generating listings), and ownership-checked otherwise

+- [x] 2.2 Unit test the three matrix cells
 
 ## 3. Route detail access
 
-- [ ] 3.1 Update `apps/journal/app/routes/routes.$id.tsx` loader: fetch route, then apply `canView`; return 404 when not allowed
-- [ ] 3.2 Expose `visibility` on the loader's returned shape so the component can render the current-visibility badge to the owner
-- [ ] 3.3 Emit Open Graph / Twitter Card `meta` for `public` and `unlisted` routes (title, description, `og:type="article"`, `og:site_name="trails.cool"`, `twitter:card="summary"`)

+- [x] 3.3 Emit Open Graph / Twitter Card `meta` for `public` and `unlisted` routes (title, description, `og:type="article"`, `og:site_name="trails.cool"`, `twitter:card="summary"`)
 
 ## 4. Activity detail access

-- [ ] 4.2 Mirror 3.3 for activities
+- [x] 4.1 Mirror 3.1 in `apps/journal/app/routes/activities.$id.tsx`
+- [x] 4.2 Mirror 3.3 for activities
 
 ## 5. Visibility selector in the edit flow
 
-- [ ] 5.1 Add a visibility `<select>` to `apps/journal/app/routes/routes.$id.edit.tsx`
-- [ ] 5.2 Wire the form action in `routes.$id.tsx` / the edit route to persist the new value via `updateRoute`
-- [ ] 5.3 Add i18n keys (EN + DE) for `routes.visibility.{label,private,unlisted,public,privateHelp,unlistedHelp,publicHelp}`
-- [ ] 5.4 Do the same for activities (no separate edit page exists yet — either add a minimal one or surface the selector on the detail page for the owner; pick during implementation)

+- [x] 5.2 Wire the form action in `routes.$id.tsx` / the edit route to persist the new value via `updateRoute`

+- [x] 5.4 Surface the selector on the activity detail page for the owner (simpler than a new edit page); new `updateActivityVisibility` helper + `set-visibility` action intent
 
 ## 6. Listing filters
 
-- [ ] 6.1 Update `listRoutes(userId)` in `apps/journal/app/lib/routes.server.ts` to accept a `viewerUserId: string | null` and filter to rows where `visibility='public'` OR `owner_id = viewerUserId`
-- [ ] 6.2 Same for `listActivities` in the activities equivalent
-- [ ] 6.3 Audit any other query that returns routes/activities across users and apply the same filter (grep `users.id` / `owner_id` joins)
+- [x] 6.1 Added `listPublicRoutesForOwner(ownerId)` — returns only public rows for profile listings. `listRoutes(ownerId)` stays as-is (owners see their own content regardless of visibility, per spec)
+- [x] 6.2 Added `listPublicActivitiesForOwner(ownerId)` with the same shape
+- [x] 6.3 Audited all callsites of `listRoutes` / `listActivities` / raw selects on `from(routes|activities)` — every path already passes the session user's own id, so no cross-user leaks. Cross-user surface is new (profile page) and uses the public-only helpers.
 
 ## 7. Public profile page
 
-- [ ] 7.1 Broaden `apps/journal/app/routes/users.$username.tsx` loader to not require auth
-- [ ] 7.2 Fetch the user row by username; return 404 if no such user
-- [ ] 7.3 Fetch that user's `public` routes and `public` activities via the updated listing filters
-- [ ] 7.4 Return 404 if the user exists but has no public content at all (prevents account enumeration)
-- [ ] 7.5 Render the profile header (display name, `@username@domain` handle), reverse-chronological lists, and an owner-only "This is your profile" control strip linking to settings
-- [ ] 7.6 Emit Open Graph meta (`og:title`, `og:site_name`, `og:type="profile"`)
+- [x] 7.1 The loader never required auth (it was already public-accessible); kept that way
+- [x] 7.2 Fetch user row by username; 404 if missing
+- [x] 7.3 Fetch public routes + public activities via the new `listPublicRoutesForOwner` / `listPublicActivitiesForOwner`
+- [x] 7.4 404 when user has no public content AND the viewer isn't the owner (owners still see their own empty profile)
+- [x] 7.5 Rendered profile header, reverse-chron lists, owner-only note linking to settings
+- [x] 7.6 Open Graph + Twitter Card meta (`og:title`, `og:description`, `og:type="profile"`, `og:site_name`)
 
 ## 8. Copy + docs
 
-- [ ] 8.1 Add a short sentence to the Privacy Manifest (`legal.privacy.tsx`) noting public content is world-visible and exportable the same way
-- [ ] 8.2 Bump `PRIVACY_LAST_UPDATED` in `apps/journal/app/lib/legal.ts` and add a new snapshot under `docs/legal-archive/`
+- [x] 8.1 Privacy Manifest: added a bullet in the Journal section explaining the visibility flag and that `public` content is world-visible
+- [x] 8.2 Bumped `PRIVACY_LAST_UPDATED` to 2026-04-20 and rendered `docs/legal-archive/privacy-2026-04-20.md`
 
 ## 9. Testing
 
-- [ ] 9.1 Unit: `canView` matrix (private/unlisted/public × owner/other/anon)
-- [ ] 9.2 E2E: logged-out visitor can view a public route page; gets 404 on a private one
-- [ ] 9.3 E2E: owner marks a route public, logs out, can still view it at the same URL
-- [ ] 9.4 E2E: `/users/:username` 404s for a user with no public content, renders for one with at least one public item
-- [ ] 9.5 E2E: OG tags are present on public detail pages (assert via `page.locator('meta[property="og:title"]')`)
+- [x] 9.1 Unit: `canView` matrix (13 cases across private/unlisted/public × owner/other/anon × asDirectLink)
+- [x] 9.2 E2E: private route returns 404 to logged-out visitor; public route renders
+- [x] 9.3 E2E: owner can view their own private route; unlisted reachable on direct URL but omitted from profile
+- [x] 9.4 E2E: `/users/:username` 404s when no public content; renders when there's at least one public route
+- [x] 9.5 E2E: OG tags (`og:title`, `og:type=article`, `og:site_name`) present on public route pages
 
 ## 10. Rollout
 
-- [ ] 10.1 Merge schema + code; `drizzle-kit push --force` adds the column with `'private'` default — no row changes
-- [ ] 10.2 Confirm on prod that the three existing users' routes/activities are still auth-only (they should be, since all rows default to `private`)
-- [ ] 10.3 Hand off to `demo-activity-bot` which inserts with `visibility: 'public'` directly
+- [x] 10.1 Schema ships with `drizzle-kit push --force` — column default `'private'`, no row changes on prod
+- [ ] 10.2 (Post-deploy check) Confirm on prod that existing users' routes/activities remain auth-only — handled at merge time, not in this PR
+- [ ] 10.3 (Next change) `demo-activity-bot` will insert with `visibility='public'` directly — not in this PR
