Privacy
This covers all fourteen apps: Proairetos, Askesis, Soma, Oikonomia, Hydros, Praxis, Theoria, Diaita, Philia, Ergon, Therapeia, Dynamis, Ktema and Phyton. What you add stays on your device. It is never read by anyone else, sold, or used for advertising.
What stays on your device
Everything you add (tasks, plans, reflections, runs, recipes, bills, drinks, study time, books and highlights) is stored in your browser on your device. You do not need an account. Proairetos has no analytics, no advertising, and no trackers, and its fonts ship with the app, so no font service sees your visits.
If you turn on sync
When sync is on, your data is encrypted on your device before it is uploaded, with a key the server never has. The server cannot read your items, notes, reflections, or schedule.
The server can see: your email address (to sign you in; with Google or Apple sign-in, the address they share); how many records you have, their rough sizes and kinds, and when they changed; the times reminders are due; and the address each of your devices uses for notifications.
Your own storage (only if you choose it)
You can sync through your own Google Drive, Dropbox or OneDrive instead. Proairetos asks for its own Proairetos folder there and can reach nothing else of yours, and writes only records encrypted on your device. Your storage company cannot read them either. The server then keeps none of your records: it holds which storage you chose and the permission to reach it, encrypted with your key, so your other devices can follow. Sign-in, reminders and shared lists still go through the server as described here.
Reminders
Your phone works out what to remind you of. The server holds only when each reminder is due and its words, encrypted with your key, so it cannot read them. Your phone opens them when the reminder arrives.
Capture from anywhere (only if you turn it on)
A Shortcut on your phone sends your words to this site with your inbox token. They are locked at once with a key only your phone holds, and kept that way until Proairetos opens them and deletes the locked copy. The server keeps a fingerprint of the token, never the token itself.
A shared list, household or care circle (only if you make or join one)
Each grocery line in Soma, each chore in an Ergon household, each plant in a shared Phyton home, and each medicine in a Therapeia care circle, is encrypted with that list’s own key, which travels only inside the invite link. The server stores them without being able to read them, and only people who joined with the link can see them.
Signing in another app from Proairetos (only if you turn it on)
Proairetos keeps a copy of your unlock key on that phone so it can make a one-time pass. The pass carries the key sealed; the key that opens it is held by the server for two minutes, given once, only to you after you sign in, and then deleted. The server never sees your unlock key itself. Signing out removes the copy.
Passkeys (only if you add one)
A passkey lives in your device's password manager (iCloud Keychain, Google Password Manager, Windows Hello). The server keeps its public key, to check that a sign-in came from it, and your unlock key sealed with a secret only the passkey gives on your device, after Face ID, a fingerprint or the device's PIN. The server cannot open it. Removing a passkey in Account removes both.
Other things that reach the internet, only when you use them
Phyton on Android may check tonight's low in the background now and then; only the place, rounded to about a kilometer, is sent to Open-Meteo. Reading text from a photo (a medicine label, a rating plate, a bill) happens on your device; the photo is not sent anywhere. Scanning a barcode in Soma sends only its number to Open Food Facts, for the product's name. Looking up a word in Theoria sends only that word to the Free Dictionary API. Recipe ideas come from TheMealDB, and a recipe link you bring in passes through proairetos.com without being stored. Distance by GPS in Askesis stays on your phone: only the distance is saved, never where you ran. A bank statement you bring into Oikonomia is read on your phone, and only money out is kept.
The waitlist (only if you join it)
If you leave your email on the front page, it is kept with the apps you ticked and the date, and used only to tell you about Proairetos and its apps. It is never sold or shared. To be taken off, reply to any email we send or write to us, and it is deleted.
Buying an app (only when you buy one)
Proairetos is free. Buying an add-on opens Stripe's own payment page (stripe.com); your card details go to Stripe, never to Proairetos. Stripe tells proairetos.com that the payment went through, and your account keeps a note of which app you bought, the amount and the date, so it opens on every device you sign in on. Nothing about what is inside your apps is involved.
Identifying a plant (only when you tap Identify)
Phyton sends the photos you chose, and which part of the plant each shows, through proairetos.com to Pl@ntNet (plantnet.org) to name the plant. Nothing else goes with them, and proairetos.com keeps nothing. Pl@ntNet is a research project; its own terms say how it treats photos sent to it. Photos you keep of a plant stay on your device. If you turn on weather for plants outside (rain, frost, hot days), only the place you choose, rounded to about a kilometer, goes to Open-Meteo.
Calendar link (only if you turn it on)
If you create a calendar subscription link, the calendar file you chose to share is the one thing the server can read, and so can anyone who has the link. By default it holds only the times of your commitments, titled “Busy”. Turning the link off deletes the file.
Other calendars (only if you add them)
If you add a Google, Apple, or Outlook calendar link, its events are shown on your device and stay there; they are never uploaded or synced. Because most calendar services block web apps from fetching directly, the calendar passes through proairetos.com on its way to you. Nothing is stored or logged there.
Weather (only if you turn it on)
Weather comes from Open-Meteo, a free service with no account or tracking. Your place is kept on your device, rounded to about a kilometer, and only that rounded place is sent to ask for the forecast. The sky at the time you write is saved with your reflections, encrypted like everything else if you sync.
Dictation (only if you use it)
If you use the microphone, your phone maker’s speech service (Apple or Google) turns your speech into text, as your keyboard’s microphone does. Proairetos asks before the first use and only ever receives the text.
Backups
Backups are files you download and keep yourself. You can lock a backup with a password, so only you can open it.
Deleting
Settings → Delete everything removes all data from your device. If you use sync, Settings → Account and sync → Delete my account removes your account and everything stored on the server.
What the app never does
It does not read, analyze, or score what you write, guess your mood, or show you advertising. Nothing you write is used to train AI.
