Privacy Policy

Version 2.0, effective 1 October 2026

§1 Who is responsible

  1. The controller for the processing described here is LESPIRANT GmbH, Karlstraße 72, 40210 Düsseldorf, Germany, represented by its managing director Laurent Tran. Commercial register: Amtsgericht Düsseldorf, HRB 77926.
  2. For any privacy question or request, write to info@lespirant.com. We have not appointed a data protection officer because the law does not require one for a company of our size.
  3. This policy covers the EventCoster website and app (eventcoster.com) and the event widget that other websites can embed.

§2 In short

  1. You can plan trips without an account. Your guest trips are linked only to a random ID stored in your browser.
  2. We use Google Analytics only if you agree. You can change your choice at any time in Privacy settings.
  3. We do not sell your personal data and we do not use it for advertising.
  4. You can download or delete your data yourself in Privacy settings, as a registered user or as a guest.
  5. The details for each purpose are below: what we process, why, on which legal basis, who receives it and how long we keep it.

§3 What we process and why

Each purpose is one block with these rows: Data, Source, Legal basis, Recipients, Transfers outside the EU, Retention. ("GDPR" = Regulation (EU) 2016/679; "TDDDG" = German Telecommunications Digital Services Data Protection Act.)

§3.1 Visiting our website (server logs)

Data
technical request data (the address of the page or API call, time, status code, response time, a request number; in error messages the address can include search parameters such as airports and dates). Your IP address is not written to our logs. To protect the service from automated abuse, our server counts the price and travel searches sent from each IP address. For this it keeps only a coded form of the address, in its memory, and never writes it to a log. For security and data-protection requests (data export, account deletion, acceptance of the Terms) the log line also contains your internal account number, never your name or email address.
Source
your browser.
Legal basis
Art. 6(1)(f) GDPR. Our legitimate interest is running the service securely and finding faults.
Recipients
Hetzner Online GmbH (Germany), which hosts our servers in Germany, as our processor.
Transfers outside the EU
none.
Retention
log files are deleted after about 8 days (one performance log after about 3 days). The servers' console output is overwritten as it fills up, so it has no fixed age; it is also deleted whenever we update the service. The search counts and the coded addresses are deleted after about 24 hours, and whenever the server restarts.

§3.2 Storage on your device (cookies and similar technologies)

Data
entries we store in your browser to keep the site working and to remember your settings: your cookie choice, the guest ID, your sign-in session and a copy of your profile, a short-lived note that you declined the Terms, the language, theme, currency, search preferences and recent airports you chose, and cached exchange rates. The full list is in our cookie policy.
Source
your browser.
Legal basis
§ 25(2) No. 2 TDDDG (strictly necessary, or stored because you asked for it). Analytics cookies are covered in §3.8.
Recipients
none while the data stays on your device. Our servers receive your sign-in token and guest ID with your requests.
Transfers outside the EU
none.
Retention
as stated for each entry in the cookie policy.

§3.3 Using EventCoster as a guest

Data
a random guest ID created in your browser; the trips you save as a guest (see §3.5).
Source
you.
Legal basis
Art. 6(1)(b) GDPR (providing the planning service you use).
Recipients
our processors Hetzner (§3.1) and Supabase (database, see §4).
Transfers outside the EU
see Supabase in §5.
Retention
until you delete the trips or erase your guest data in Privacy settings. If a guest trip has not been changed for 12 months, we anonymise it: we replace the guest ID with a random ID that cannot be linked to you or to your other trips, and we delete your notes and trip names. The remaining data (event, airports, dates, number of travellers, chosen offers and costs) is then anonymous and kept for statistics. If you clear your browser storage, the guest ID is lost and you can no longer see or erase those trips yourself; they are anonymised after 12 months.

§3.4 Your account and sign-in

Data
email address and name from your Google or LinkedIn profile, an account number, the ID of your sign-in identity, your home city and default search preferences, and the dates your account was created and changed.
Source
Google or LinkedIn, when you sign in with them, and you.
Legal basis
Art. 6(1)(b) GDPR (the contract under our Terms of Service).
Recipients
Supabase (database and sign-in service, see §4); Hetzner (§3.1). Google or LinkedIn, which you use to sign in, process your sign-in under their own privacy policies. Our administrators can see account names and email addresses with the number of trips and recent trip activity (event and trip status), and can export this list.
Transfers outside the EU
see Supabase, Google and LinkedIn in §5.
Retention
until you delete your account in Privacy settings or decline the Terms. Deleting the account deletes your trips, your account and your sign-in identity in one step. If deleting the sign-in identity fails, nothing is deleted and you can try again.

§3.5 Planning trips and price estimates

Data
the event you plan to attend, your departure city and airport, travel dates, number of adults and children, budget and filters, the flight, hotel and package you choose, offer details, and any notes or trip names you enter.
Source
you.
Legal basis
Art. 6(1)(b) GDPR.
Recipients
Hetzner and Supabase (§4). To get prices, our server sends the search details (airports, dates, number of travellers, hotel location) to travel data providers (§4). It never sends your name, email, account number or guest ID, and the providers do not receive your IP address.
Transfers outside the EU
see §5.
Retention
with your account (§3.4) or guest data (§3.3). You can delete a trip at any time; a trip with a confirmed booking is archived instead and deleted with your account or guest data. You can keep at most 500 planned trips at a time.

§3.6 Accepting our Terms of Service

Data
the version of the Terms you accepted and the time (server time). We check that you confirmed being 18 or older but do not store that confirmation separately.
Source
you, on the acceptance page.
Legal basis
Art. 6(1)(b) GDPR (the contract) and Art. 6(1)(f) GDPR (proof that you accepted).
Recipients
Hetzner and Supabase (§4).
Transfers outside the EU
see Supabase in §5.
Retention
with your account.

§3.7 Your cookie choice (consent records)

Data
your choice for Google Analytics, the version of our cookie banner, the date, and your account number or guest ID. No IP address and no browser details.
Source
you, through the cookie banner or Privacy settings.
Legal basis
Art. 6(1)(c) GDPR together with Art. 7(1) GDPR (we must be able to show your consent).
Recipients
Hetzner and Supabase (§4).
Transfers outside the EU
see Supabase in §5.
Retention
13 months, then deleted automatically. If you delete your account or erase your guest data, we keep only a minimised record (your choice, the version and the date, with your account number or guest ID replaced by a code that we cannot turn back into it) until the 13 months have passed, to prove which choice was made (Art. 7(1), Art. 17(3)(e) GDPR).

§3.8 Google Analytics (only with your consent)

Data
if you allow Analytics, Google Analytics 4 sets cookies (_ga, _ga_…) and receives the pages you view (the page address without its parameters, except campaign tags such as utm_source, and the page title) and how you use them: how far you scroll down a page, the search terms you enter in our site search, when you start and submit a form (not what you type into it), and the name and link of files you download. Google also receives your IP address and browser details. We do not send your name, email, account number, guest ID or trip numbers, and advertising features stay switched off.
Source
your browser.
Legal basis
your consent, § 25(1) TDDDG and Art. 6(1)(a) GDPR. You can withdraw it at any time with effect for the future in Privacy settings; we then stop Google Analytics and delete its cookies. Without your consent, Google Analytics is not loaded at all.
Recipients
Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, as our processor.
Transfers outside the EU
Google may transfer data to Google LLC in the USA (§5).
Retention
the cookies last up to 2 years or until you withdraw consent. Google keeps the analytics data for 2 months.

§3.9 Maps and hotel photos

Data
when a page shows a map or a hotel photo, your browser loads it directly from the provider, which receives your IP address and browser details. For hotel photos we tell your browser not to send the address of our page.
Source
your browser.
Legal basis
Art. 6(1)(f) GDPR. Our legitimate interest is showing maps and hotel photos without hosting them ourselves.
Recipients
OpenStreetMap Foundation, St John's Innovation Centre, Cowley Road, Cambridge, CB4 0WS, United Kingdom (map tiles); Booking.com B.V., Amsterdam, Netherlands (hotel photos, loaded from its image servers). Both decide themselves how they use these requests.
Transfers outside the EU
OpenStreetMap Foundation is in the United Kingdom, which has an EU adequacy decision.
Retention
we store nothing. The providers' own privacy policies apply.

§3.10 Partner links

Data
some booking links lead to partner sites (Booking.com, Skyscanner, Expedia, Hotels.com, Aviasales/Travelpayouts, or an event's own ticket shop) and may earn us a commission. The link contains your search (for example airports and dates) and our partner ID. We do not add your name, email, account number or guest ID, and we do not record your clicks.
Source
your search.
Legal basis
Art. 6(1)(b) GDPR (building the links you asked for).
Recipients
when you click, your browser opens the partner's site. From then on the partner processes your data under its own privacy policy. We tell your browser not to send the address of our page.
Transfers outside the EU
depends on the partner; see its privacy policy.
Retention
we store nothing about the click.

§3.11 Example trip on our home page

Data
our home page shows one real trip as an example: the event, its dates and place, the departure and destination airports and the estimated costs (flight, hotel, ticket and total). We never show who planned the trip.
Source
the trips saved on EventCoster (§3.5), registered or guest.
Legal basis
Art. 6(1)(f) GDPR. Our legitimate interest is showing new visitors what a complete trip plan looks like. You can object at any time (§7).
Recipients
everyone who visits the home page.
Transfers outside the EU
the page is public.
Retention
the example is chosen again every day from the most recent complete trip; it is not stored separately.

§3.12 Emails to us, reports and rights requests

Data
your email address and name, your message and any details you send, for example when you contact us, report content on an event page, or exercise your rights.
Source
you.
Legal basis
Art. 6(1)(f) GDPR (answering you); for rights requests Art. 6(1)(c) GDPR (our legal duty to answer).
Recipients
Google Ireland Limited (Google Workspace), which hosts our email, as our processor.
Transfers outside the EU
see Google in §5.
Retention
as long as needed to handle your message, and longer only where the law requires it (for example commercial or tax retention periods).

§3.13 People named in event information

Data
our event pages describe public events using information from organisers' websites and event directories. Descriptions can name performers, teachers, DJs or organisers, and event entries can hold the organiser's name and the event's social-media accounts. We translate descriptions automatically.
Source
publicly available websites and event directories, not the people named. This section is our information under Art. 14 GDPR.
Legal basis
Art. 6(1)(f) GDPR. Our legitimate interest is informing travellers about public events.
Recipients
everyone who visits the event pages; our processors Hetzner and Supabase; Google (Gemini) and Mistral AI, which we use to translate and check event information; and search and AI services we use to import and check event information (for example DuckDuckGo, Serper, Tavily, Jina AI and DeepSeek), which receive event information only.
Transfers outside the EU
see §5.
Retention
as long as the event is listed. If you are named and want a correction or removal, use "Report content" on the event page or write to info@lespirant.com.

§4 Recipients and processors

  1. We use these processors, bound by data processing agreements (Art. 28 GDPR):
    • Hetzner Online GmbH, Gunzenhausen, Germany: server hosting in Germany.
    • Supabase Inc., USA: database and sign-in service, hosted in an EU data centre.
    • Google Ireland Limited, Ireland: Google Analytics (only with consent) and Google Workspace (email).
    • Google (Gemini API) and Mistral AI (France): translation and checking of event information; no data about you as a user.
  2. Travel data providers that our server queries for prices (search details only, never your identity): Booking.com, Google Flights, Kiwi.com and Skyscanner data through RapidAPI, Travelpayouts, and an exchange-rate service. Services our administrators use to check event information receive event details only: DuckDuckGo (web search) and OpenStreetMap Nominatim (address lookup).
  3. Independent recipients your browser contacts directly: Google and LinkedIn when you sign in with them; the OpenStreetMap Foundation (maps); Booking.com (hotel photos); our partners when you click a partner link.
  4. Our source code and event data are stored with GitHub, Inc. (USA).
  5. We disclose data to authorities only where the law obliges us to.

§5 Transfers outside the EU

  1. Supabase Inc., Google LLC and GitHub, Inc. are based in the USA. Where data is transferred to the USA, the transfer is based on the EU-US Data Privacy Framework (for certified companies) or on the EU standard contractual clauses in our agreements with them.
  2. The OpenStreetMap Foundation is in the United Kingdom, which the European Commission recognises as providing adequate protection.
  3. Partners you visit through a partner link, and Google or LinkedIn when you sign in with them, process data under their own policies, which describe their transfers.

§6 How long we keep data (overview)

DataRetention
Account, sign-in identity, tripsUntil you delete your account
Guest tripsUntil you delete them; anonymised after 12 months without changes
Cookie choice records13 months; after deletion only a minimised record
Server log filesAbout 8 days (console output: overwritten as it fills up)
Google AnalyticsCookies up to 2 years; data at Google 2 months
EmailsAs long as needed, plus legal retention periods
Data on your deviceSee the cookie policy

Copies in our providers' backups are overwritten in their regular backup cycle.

§7 Your rights

  1. You have the right to access your data (Art. 15 GDPR), to have it corrected (Art. 16), deleted (Art. 17) or restricted (Art. 18), and to receive it in a portable format (Art. 20).
  2. Right to object (Art. 21 GDPR): where we rely on our legitimate interests (Art. 6(1)(f)), you can object at any time for reasons arising from your particular situation. We then stop unless we have compelling legitimate grounds or need the data for legal claims.
  3. Withdrawing consent: you can withdraw your consent to Google Analytics at any time in Privacy settings. This does not affect the lawfulness of processing before the withdrawal.
  4. Do it yourself: in Privacy settings you can download your data and delete your account, or, as a guest, download and erase your guest data. You will see a receipt listing what was deleted and what we keep, and why.
  5. Or write to info@lespirant.com. We answer within one month (Art. 12(3) GDPR).
  6. Right to complain: you can complain to a supervisory authority, in particular in the EU country where you live or work, or to ours: Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen (LDI NRW), Kavalleriestraße 2–4, 40213 Düsseldorf, Germany, www.ldi.nrw.de.

§8 Global Privacy Control and Do Not Track

  1. We honour Global Privacy Control (GPC). If your browser sends the GPC signal, we treat it as a refusal of analytics: Google Analytics is not loaded and cannot be switched on while the signal is present.
  2. We do not track you across other websites, so we do not react to "Do Not Track" signals beyond that: without your consent, no analytics run at all.

§9 Do we sell your data?

  1. No. We do not sell personal data and we do not share it for advertising.
  2. Partner links may earn us a commission. When you click one, your browser sends the partner the link (with your search and our partner ID) and your IP address, as with any website you open. We add nothing that identifies you.

§10 Automated decisions

We do not make decisions based solely on automated processing that have legal or similarly significant effects on you (Art. 22 GDPR). Our rankings of flights, hotels and events are explained on How we rank results.

§11 Age

EventCoster is intended for people aged 18 and over (our Terms of Service).

§12 Security

We protect your data with technical and organisational measures, for example: verified sign-in, access only to your own trips, no IP addresses, names or email addresses in our logs, analytics only with consent, and limited administrator access.

§13 Changes to this policy
