Legal & Privacy

1. Controller and contact

The controller is Weifeng Zhang. The postal and contact addresses are provided above in the Legal notice. Please use the same email address for privacy enquiries.

2. Functions used by this website

PARAFROG is a private website without advertising, sales or paid partnerships. The new website provides photographs, texts and its own video files. It has no visitor accounts, comments, contact forms, newsletters, advertising pixels or analytics tools such as Google Analytics or AdSense. Fonts and preview images are served with the website. The optional Google map, which you must explicitly activate, is an exception described in section 6.

Ordinary page visits, image downloads and playback of the site's own videos generate technically necessary connection data. It would therefore be incorrect to state that no personal data is processed at all.

3. Website delivery and server logs

SiteGround hosts this website. The account identifies Frankfurt, Germany, as the primary server location and shows the free SiteGround CDN as active. Delivery, troubleshooting and security processing rely on GDPR Article 6(1)(f), with the legitimate interest of operating a secure, functioning website.

Connection data may include IP address, request time, requested page, status code, referrer and browser information. SiteGround also provides server-side visitor statistics. This website does not additionally install Google Analytics or advertising trackers.

The SiteGround data processing agreement names SiteGround Spain S.L., Calle de Prim 19, 28004 Madrid, Spain, and forms part of its service terms. It provides standard contractual clauses for applicable non-EEA transfers. CDN delivery may use global locations; a German primary server does not mean all processing stays in Germany. See location information.

SiteGround documents access-log retrieval for up to 30 previous days in its access-log guide. This is not a deletion deadline for all security records, statistics or backups. Records needed for incidents, legal duties or legal claims are kept as long as necessary for those purposes.

4. Contacting me

If you contact me by email, the contact details, message content and related technical communication data you send are processed to handle your enquiry. The legal basis is Article 6(1)(f) GDPR; the legitimate interest is responding to and appropriately documenting incoming enquiries. Enquiries exercising data-protection rights are processed to fulfil legal obligations under Article 6(1)(c) GDPR.

Providing your data is voluntary. A personal reply may not be possible without a reachable reply address. Messages are deleted once the enquiry has been fully handled, unless necessary further retention, a legal obligation or the defence of legal claims requires otherwise.

SiteGround provides the [email protected] mailbox. Sending, receiving and storing messages involves sender and recipient details, message contents and technical communication data. The processing and transfer arrangements described above apply. A separate physical mailbox location was not displayed in the account; the website server location is not a guarantee of the mailbox location.

5. Cookies, local storage and the site's own videos

The personal flying-places map uses map files, destination data and photos served by this website. Zooming, dragging, marker grouping and photo previews run in your browser without a third-party map service or reporting these interactions to me. It is separate from the optional Google My Maps described below.

The website scripts I provide do not set analytics or advertising cookies or store visitor profiles in Local Storage. Navigation, photo enlargement and image animations run in your browser without sending corresponding interaction logs to me. Your browser may retain files in its ordinary cache.

The site's own flight videos are loaded as files from the same website host. Playback contacts the server and technical infrastructure of that host; section 3 applies. No YouTube player is embedded for this purpose. The optional Google map behaves differently.

Where access to your device is strictly necessary for a service you expressly request, the exemption from consent requirements is governed by section 25(2) TDDDG. Consent for the optional map is obtained separately.

6. Google My Maps — only with your consent

You may choose to display the Alpine map as a Google My Maps map. Google services in the European Economic Area are provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.

No map iframe is loaded on these pages before you click “Load Google map”. Clicking gives your consent to the embedding. In particular, your IP address, browser and device information, the page visited and map interactions may then be transmitted to Google. Google may use cookies or similar technologies and associate data with your Google account if you are signed in. The purpose is to display flying sites interactively.

The legal bases for the embedding I initiate are your consent under Article 6(1)(a) GDPR and, where information is stored on or read from your device, section 25(1) TDDDG. The rest of the website remains usable without consent.

Google and affiliated companies may process data in the USA and other third countries. In its information on international data transfers Google explains the mechanisms used, including the EU–US Data Privacy Framework for covered, certified US recipients and, where applicable, standard contractual clauses. Further information on purposes, retention and settings is available in the Google Privacy Policy.

You may withdraw consent to further loading of the embedded map at any time by choosing “Close map”. This removes the embedding; processing already carried out is unaffected. Activation is not saved on this website for future visits. Closing does not remove data already set by Google; manage it through your browser and Google settings. On a new page visit, the map is again loaded only after you click.

7. External videos, social networks and QR codes

Videos by other creators on YouTube, and Instagram, Facebook, WeChat and other external services are linked. Their preview images and logos are stored within this website. Simply viewing these links or the locally stored WeChat QR codes does not cause the website to load an embedded player or social-media plugin from the respective provider.

If you open an external link, or scan a QR code with another app and visit its destination, the respective provider's data processing and privacy information apply. The destination then receives the connection data required for the visit. If you contact me via a social network, I process the information you send in order to reply; the platform provider is responsible for processing by the platform.

8. Published photographs and videos

Photographs and videos document personal travel, flying and public events. The basis for publishing identifiable people depends on the image and context: consent under GDPR Article 6(1)(a), or, where applicable, legitimate interests under Article 6(1)(f) after balancing expression and documentation against individual rights. German portrait-law exceptions for event coverage or incidental appearances apply only where their conditions are met and legitimate personal interests are respected. Attendance at a public event does not itself authorize every use of a portrait. Contact me with the relevant page and image to object or request review. Consent may be withdrawn for future processing.

9. Recipients and retention

Technical recipients include SiteGround and processors involved in hosting, CDN delivery, email and support; see section 3 for processing and transfer arrangements. Enabling Google Maps also involves the Google service described in section 6. Information may be disclosed to relevant bodies where necessary for legal duties or legal claims. I do not arrange commercial marketing with visitor data.

Personal data is retained only as long as its purpose or a legal obligation requires. The relevant periods or criteria are described for each processing activity. For retention periods determined by Google or other independent platform providers, consult their privacy notices.

10. Your rights

Where the legal requirements are met, you have rights of access, rectification, erasure, restriction of processing and data portability under Articles 15–20 GDPR. You may withdraw consent at any time with effect for the future. Please use the contact in section 1 for requests.

You also have the right to lodge a complaint with a data-protection supervisory authority, particularly where you live, work or believe an infringement occurred (Article 77 GDPR). A directory of German authorities is provided by the German Data Protection Conference. This website makes no automated decisions with legal or similarly significant effects and performs no corresponding profiling.

11. Changes

This statement will be updated when website functions, providers or relevant circumstances change. For additional services such as a newsletter, contact form or a new embedded service, the relevant information will be added before those services are used.

12. Notes & Liability

Reference information only

This private website provides general, non-binding information and shares personal flying experiences. No guarantee is given as to the accuracy, completeness or currency of its information. This applies in particular to descriptions of flying sites and take-off areas, take-off directions, elevations, wind and weather, airspace, access, cable cars, fees, contacts, and flight-school and club directories.

No flight clearance or substitute for a briefing

This information is neither a personal flight recommendation nor permission to take off, land or enter a site. It does not replace qualified training, a local introduction or required briefing, or current site and operating rules. A stated take-off direction does not establish that launching in a particular wind is safe, permitted or appropriate for your ability.

Check current local requirements

Flight preparation and execution must take account of applicable regulations, current information from site operators, local clubs and schools, and actual conditions on site. Confirm briefings, visitor rules, registration, qualifications, proof of insurance and any required tickets or fees directly with the responsible organisation. Pilots still in training must follow the instructions of their authorised flight school.

Weather, airspace and emergencies

Wind, weather, airspace restrictions and local closures can change at short notice. Information displayed or linked here is no assurance of current conditions. Emergency numbers and contact details are also provided for orientation; official information for the country concerned and local rescue guidance are authoritative when preparing a trip.

Sources, directories and archive material

A source or access date records when research was carried out; it does not indicate continuous monitoring. Linked original sources may later change or become unavailable. Naming a school, club or service does not guarantee its current authorisation, availability or suitability. Archive photographs and videos show personal experiences and do not establish present flying conditions or current permission to fly.

Statutory liability

These notes explain the informational nature of this website. Mandatory statutory liability remains unaffected; no legally impermissible exclusion of liability is intended.
