← OVERHEAD
Privacy Policy
overhead.world · last updated 18 June 2026
Note: this is a good-faith draft describing how OVERHEAD
actually handles data. It is not legal advice. Because OVERHEAD processes location data and
serves visitors internationally, have it reviewed by a qualified professional, and confirm the pre-filled operator, jurisdiction and contact details, before relying on it.
OVERHEAD ("the App", "we", "us") is a browser-based live sky projector at
overhead.world, operated by Jash Patel.
This policy explains what data the App touches and why. OVERHEAD is designed to be
privacy-first and stateless: it has no user accounts, and it does not store
your location or build a profile of you.
Location
- If you allow it, the App reads your approximate position through your browser's
Geolocation API, purely to calculate the sky above you.
- Your coordinates are processed in your browser and held only for the
current session. We do not save them to a database or associate them with you.
- To turn coordinates into a place name, an approximate, rounded coordinate is sent to the
OpenStreetMap Nominatim geocoding service (via our proxy).
- To show nearby aircraft, your coordinates are sent to the adsb.lol
aircraft-data service (via our proxy).
- If you deny location, the App still works — you set a location yourself via ZENYTH, and
nothing is read from your device.
Our proxy & server logs
Requests to the data services above are forwarded through OVERHEAD's own caching proxy. As
with any internet service, the underlying hosting infrastructure may transiently log standard
request metadata (such as IP address and the requested URL) for operation and abuse-prevention.
This is not used to track you or build a profile, and the proxy only ever talks to three
allow-listed hosts (adsb.lol, wheretheiss.at and Nominatim). Routing the ISS feed through
the proxy also keeps your IP address off that provider.
On-device storage
- The App uses your browser's local storage to remember a few preferences (e.g. render
scale and time-lapse settings). This stays on your device.
- Time-lapse recordings are created and stored locally (your Downloads
folder and a private in-browser file area). They are never uploaded to us.
- The optional mobile facing compass reads your device's orientation
sensor when you enable it (a tap, which on iOS also grants sensor permission). That
reading is used live, on your device, only to show which way you're
facing — it is never stored or transmitted. The separate orient control
that rotates the sky is set by hand (a dial or a typed bearing) and uses no sensor.
Analytics
The only analytics OVERHEAD uses is Vercel Web Analytics,
the first-party, privacy-focused analytics built into our host. We use no other analytics, and no
advertising or behavioural tracking of any kind.
- It is cookieless — it sets no cookies and stores nothing on your device to
identify or follow you.
- Visitors are counted using a temporary hash derived from the incoming request, which is
reset every 24 hours, so you cannot be tracked across days, sessions, or
other websites.
- Only anonymous, aggregated figures are recorded — for example page views,
referrer, country and browser/device type. No IP address or personal identifier is stored
against this data, and an individual's browsing cannot be reconstructed from it.
Full details are in Vercel's
Web Analytics privacy notice.
What we do not do
- No accounts, sign-in, or passwords.
- No advertising, no cross-site tracking, and no tracking cookies.
- No selling or sharing of personal data.
- Fonts are self-hosted — no request is made to Google Fonts or any font CDN.
Third-party services
When the App contacts adsb.lol, wheretheiss.at or OpenStreetMap/Nominatim, those services
receive the request and operate under their own privacy terms. See the
attribution notice for links.
Your rights (UK/EU GDPR)
Because the App does not store personal data about you, there is normally nothing for us to
retrieve, correct or erase. Where applicable, the lawful basis for reading your location is your
consent, which you can withdraw at any time in your browser. To make a request or ask a
question, contact us below. You may also complain to your local data-protection authority
(in the UK, the ICO).
Children
OVERHEAD is a general-audience tool and is not directed at children. It does not knowingly
collect personal data from anyone.
Changes
We may update this policy; the "last updated" date above reflects the current version.
