The short of it
Petrichor keeps a journal for you and keeps it to itself. No account, no advertising, no analytics, no network use. Your entries, your tags, your charts and your settings are written to the app's own storage on your phone.
Every other section on this page is a detail of this one.
Who the controller is
SHABEER PLUMBING LTD, trading as IronCedar Interactive, 72 Basildon Avenue, Ilford IG5 0QQ, United Kingdom; director Shabeer Ziarmal. That company is the controller of any personal data described here, under the UK GDPR and the Data Protection Act 2018. The address for everything below is dawn@shabeerplumbing.hair.
The trading name on the app and the registered name on the invoice are the same company.
What a journal entry contains
- the date and time you logged, the sky state you chose and how the air felt;
- the wind direction you set on the rose and the strength you judged;
- your own line of notes, and any old signs you tagged;
- everything the patterns page derives from those entries.
A run of dated entries says where somebody was and when they were outside, so it stays on the device. There is no server to receive it, no account it hangs from and no way for us to read it. Your own Android backup at Google may carry a copy if you have that turned on, under your account rather than ours.
This is the sensitive part of the app, which is exactly why it never leaves the phone.
What the app asks of the phone
No permissions at all. It does not read your location, so the entries are placed only by whatever you write yourself; no camera, no microphone, no contacts, no files, and no connection out.
A weather app that asks for nothing is unusual. It is deliberate.
Nothing measured about you
No sign-in, no advertising identifier, no analytics events, no crash SDK of ours, no profiling. We do not know how many entries anybody keeps or whether the app is opened at all.
Which also means we cannot recover your journal if you lose the phone.
Google Play's part
The download runs through Google Play on Google's own terms. Where a device sends usage and diagnostics to Google, aggregate crash and performance figures may appear on our Play Console. They identify nobody and we read them to find faults.
The only third party anywhere near this app.
Children
Nothing is collected from users of any age, and there is no chat, no link out and nothing to buy. Watching the sky is a decent habit to give a child; writing a place name in an entry is worth a word of caution from a grown-up.
Entries are free text, so they hold whatever gets typed into them.
Lore, and the actual weather
Petrichor is folklore and a notebook. It measures nothing, forecasts nothing, and the honest notes beside each saying are history rather than prediction. Never decide whether to sail, climb, drive, fly a drone or bring the animals in on the strength of a proverb or your own past entries.
For real weather in the UK use the Met Office forecast and its warnings, and coastal and mountain forecasts where they apply. If you go looking for a halo or a sun dog, keep the sun itself hidden behind a roof or a tree: never look at it directly, and never through binoculars or a camera. In an emergency call 999, or 112.
The app says the same thing on its own patterns page. It is the one line worth repeating.
If you write to us
An email hands over your address and your message. We use them to answer you and to correct the almanac, on the basis of our legitimate interest in replying to correspondence, and we delete the thread within twelve months of the last reply unless the law requires longer.
Regional sayings sent in this way are the best post we get.
Rights, and the regulator
Access, rectification, erasure, restriction, objection and portability apply in full, although correspondence is the only file we could produce. Ask and we answer within a month. If the answer disappoints you, the Information Commissioner's Office takes complaints at ico.org.uk or on 0303 123 1113.
Your journal is outside all of this: we never hold it.
Clearing the journal, and edits here
Open the app's entry in Android settings, go to storage and clear the data, and the journal, the tags and the charts go together; uninstalling does the same. Nothing can be restored afterwards, so export or photograph anything you care about first. This page is rewritten, with a new date at the top, before any release that changes how the app handles data.
A season of entries takes a season to rebuild. Be sure.
