Privacy policy
Last updated: 2026-11-11
This policy describes the Valdill app for iPhone. Valdill is published by William Peter Huggins. Questions go to support@valdill.info.
In short
- There is no account. Your jars, logbook, corrections, places and city are stored only on your iPhone.
- The app sends a small amount of data to make three things work: the temperature for outdoor places, a check for a required update, and push notifications. It also sends the messages you write to us from the in-app help.
- There is no advertising, no analytics, no crash reporting, no advertising identifier and no tracking across apps or websites.
What stays on your iPhone
Everything you build in Valdill: jars and what went into them, where each jar stood, the logbook and your taste marks, the corrections learned from them, the places and temperatures you set, the salt and spoon you chose and the city. None of it is uploaded, backed up by us or visible to anyone else. Daily reminders are scheduled on the iPhone itself and are not sent through any server.
What leaves your iPhone
| What | Sent to | Why | Kept |
|---|---|---|---|
| The text you type to search for a city, and the coordinates of the city you picked | Open-Meteo (open-meteo.com), a free weather service | To find the city and fetch hourly temperature and sunshine for balcony, windowsill and cellar | Not by us; Open-Meteo answers the request. No identifier is sent with it. Your device's own location is never used. |
| An identifier for the app on this device (the push subscription ID, or Apple's identifier for vendor when push is off), the app's bundle identifier and version | Our server at api.valdill.info, run on Cloudflare | Once per launch, to learn whether this version is current or a newer one is required | Used to answer that request only. It is not linked to your name or email. |
| Push token, device model, iOS version, language, time zone, app version, the identifier for vendor, and two labels: whether this is a first install and which screen the app opened to | OneSignal, Inc. (onesignal.com), our push notification provider | To deliver notices about the app | Kept by OneSignal while the app is installed and push is in use; deleted on request |
| A message you write in Help and feedback, with any photos or files you attach, the email you give for a reply, and device details if that switch is on (app version, iOS version, device model, language) | Our server at api.valdill.info, which forwards it by email through Cloudflare to our support inbox and keeps no copy | To read and answer your message and fix what it reports | In the inbox for as long as needed to answer, at most 12 months; deleted earlier on request |
Nothing is sent from the help screen until you press Send. Photos you attach are re-encoded, which removes location data from them. If our server cannot be reached, the app offers to send the same message from your own Mail app instead.
What we do not collect
Your name, phone number or address; your device's location; contacts; browsing history; purchases or payment details; the advertising identifier (IDFA); analytics events; crash logs. Valdill does not show the App Tracking Transparency prompt because it does not track you.
Notifications
Valdill asks for permission to send notifications only when you turn on the daily reminder in Settings → Preferences. You can turn notifications off at any time in the iPhone's Settings → Notifications → Valdill, or switch off the reminder in the app.
Web pages inside the app
This policy opens in an in-app browser. If a required update is announced, the app may also show a page from api.valdill.info in an in-app view. Like any browser, these views can store cookies and local data for that page on your iPhone.
Children
Valdill is rated 4+ and contains nothing unsuitable for children, but it is a kitchen tool for adults and is not directed at children. We do not knowingly collect personal data from children.
Keeping and deleting your data
- Settings → Your data → Erase everything removes every jar, the logbook, corrections and the city from your iPhone. Deleting the app does the same.
- To have a help message or your push record at OneSignal deleted, write to support@valdill.info. We will delete it within 30 days.
Where the data goes
Cloudflare runs its network in many countries. OneSignal is based in the United States. Open-Meteo runs its own servers in Europe. Data sent to these services may be processed outside your country, under each provider's own safeguards.
Your rights
You can ask what we hold about you, ask for it to be corrected or deleted, and object to its use. Write to support@valdill.info; we answer within 30 days. You can also complain to the data protection authority where you live.
Changes to this policy
If the app starts sending anything new, this page is updated before that version is released, and the date at the top changes.
