Privacy notice

If you never sign up for alerts

There is no account and nothing about you is written to our database. Two things do happen in your browser, and both are described in full below: Microsoft Clarity sets cookies and records how the page is used, and if you pick a city with the location control the site remembers that choice in your browser's local storage so you do not have to pick it again.

To answer "is tonight worth it where you are", the server reads the approximate location that Cloudflare attaches to your request at the edge — roughly city-level, derived from your IP address. It is used to compute the answer and is not written to any database or log by this site. If you would rather not use it at all, pass explicit coordinates in the URL instead: /tonight/?lat=22.28&lon=114.17.

If you sign up for peak alerts

Three things are stored, and only these three:

• Your email address, so the alert can be sent.
• Coordinates rounded to two decimal places — about a kilometre. That is precise enough to compute a radiant altitude and pull the right cloud forecast, and too coarse to identify an address. Rounding happens before the value is written, so the precise figure is never stored. This field is optional; untick the box on the form and you will get peak dates without a location.
• Your time zone, so "tonight" means your tonight rather than UTC.

No name, no IP address against your subscription, no browsing history, no open or click tracking beyond what the sending provider records to deliver the message.

Confirmation and unsubscribing

• Sign-up is double opt-in. Nothing is sent to you until you click the link in the confirmation email. Unconfirmed addresses are never added to the sending pool and are deleted after 30 days.
• Every email carries a one-click unsubscribe link and the standard List-Unsubscribe headers, so your mail client's own unsubscribe button works too.
• Unsubscribing deletes the record. It is not flagged as inactive and kept.
• You will get at most two emails per shower per year: one about a week before a peak, and one on the evening itself. If the verdict for your location that night is poor, the second email is replaced by one naming the next good night — the same suppression logic the site uses, applied to your inbox.

Analytics

This site uses Microsoft Clarity to understand how pages are actually used — which parts people read, where they get stuck, and what they click. Clarity records page views, clicks, scrolling and mouse movement, and can replay that as an anonymised session. It is used to make the site easier to use; it is not used for advertising, and no data from it is sold or shared for marketing.

Clarity sets cookies in your browser to tell one visit from another. Microsoft acts as a data processor here and its handling is covered by the Microsoft Privacy Statement. Their notes for site visitors are at clarity.microsoft.com/terms.

To be straight with you about where this stands: analytics cookies are the kind that, for visitors in the EU and UK, should be asked about before they are set. This site does not yet show a consent banner, so for now the honest position is disclosure rather than consent — this section is that disclosure. A consent mechanism is on the list. Until it ships you can block the cookies with your browser's own controls, or opt out of Clarity and other Microsoft analytics at Microsoft's opt-out page; the site works exactly the same either way.

There is no Google Analytics, no advertising pixel and no ad network on this site.

Advertising and affiliate links

There are currently no affiliate links and no advertising anywhere on this site.

If either is ever introduced, these rules apply and are worth holding us to: any page carrying a paid or commission-earning link will say so visibly, above the link and not in a footer; every such link will carry both the sponsored and nofollow link relations so that search engines are told it is paid; and this notice will be updated before the first link goes live rather than after. No verdict, rate or recommendation on this site will ever depend on whether a link earns anything.

Who else sees your data

• Cloudflare hosts the site and processes requests at the edge, and stores the subscriber records.
• The email delivery provider receives your address in order to deliver the alert.
• Microsoft receives the Clarity analytics described above: how pages are used, plus the technical details any web request carries, such as your IP address and browser.
• Weather providers receive a coordinate rounded to a 0.1° grid — about 11 km — with no identifier attached to it. They cannot link a query to a person, and neither can we.

Nothing is sold, rented or shared for marketing purposes.

Your rights

Email contact@meteorshowercal.com from the address you subscribed with to see, correct, export or delete what is held. Because the stored record is an email address, two decimal places of latitude and longitude, and a time zone, this is usually a one-line answer. Deletion is immediate and not reversible.

Children

The site is not directed at children and no alert sign-up should be made by anyone under 13. If you believe a child has subscribed, email the address above and the record will be deleted.

Changes

Material changes to this notice — in particular the introduction of advertising or affiliate links, or any new category of stored data — will be published here before they take effect. Subscribers will be told by email if what is stored about them changes.
