Astera keeps the journal you design and the reason you made it. This page lists everything it stores, where it sits, and how to take it back.

What the website holds

• Your email address, used to sign you in. There is no password to store.
• The journal you build, which is the layout, the words on your pages and any photographs you place into them.
• An order, if you buy a book: what you ordered and what the printer needs to post it. Payment is taken by Stripe, and card numbers reach Stripe rather than us.
• Your email address and your eight scores, if you ask for your wheel of life to be sent to you from the front page. That is one email, sent because you asked for it. You are not put on a list, nothing follows it, and the address is kept only so a message that failed to arrive can be sent again. Ask us and it is deleted.
• Where you came from, when you make an account: the website that sent you, the tag on the link you followed, the company that ran the ad if an ad brought you, and the first page you opened. It is kept with your account so we can see which posts bring people to Astera. A question you ask in the chat reaches us with it too.

When an assistant plans your journal

You can plan your journal with an assistant such as ChatGPT or Claude. If it uses Astera's connector, it sends us your answers to the twelve questions, a title and any lines for your vision board, and we keep them as a draft. Your conversation never reaches us, and neither does anything else the assistant holds.

The assistant gives you a link to the draft, and the link works for 30 days. Open it and sign in, and the answers go into your account. A draft nobody opens is deleted 30 days after its link runs out. If the assistant writes your answers straight into a link instead, the page takes them off the address before anything counts the visit.

We also keep the address the call came from, so one machine can't start drafts all day. The connect page lists what the connector does.

What the companion app holds

• Your email address, the same one. You type it in to get a sign-in code.
• An account id, made the first time you sign in. It ties everything below to you.
• The lines you record or write. A recording is kept as an audio file and a written line as text.
• The photographs you add beside a line, taken with your camera or picked from your photo library. Each one keeps its caption, the line it sits beside, and the date it was taken if your phone saved one.
• The quotes and reminders you write yourself, and which quote packs you added.
• The times you chose for your morning line, and how you want it shown.
• Where the app was installed from, as Google Play reports it, such as a search in the store or a link we posted. It is kept with your account. The iPhone app doesn't collect this.

The app asks for your microphone the first time you press record, and for your camera or photo library the first time you add a photograph. It reads only the photograph you pick. You can still write your lines if you say no.

Recordings and photographs sit in private storage. They are reachable through a link that expires, and only for the account that made them.

The app has no analytics, crash reporting or advertising code in it.

What we use it for

• Your email address signs you in with a code. We also use it to send you what you asked for: an order email, your wheel of life, or a reply when you write to us.
• We send up to three emails about the next step when a journal in the workspace is left unfinished. Each one has a link to stop them.
• The app shows you your lines, recordings and photographs, and plays one back each morning at the time you chose. The same answers open in your journal on the website.
• Where you came from tells us which posts bring people to Astera. We get an email when a new account is made, with its address and where the person came from.
• An order goes to the printer, who makes your book and posts it to you.
• A message you send in the chat reaches us so we can answer it.

Who else holds it

Your account and everything in it are stored on Supabase in Ireland, on servers inside the European Union. Supabase runs the sign-in too.

These companies each do one job for us:

• Resend, also in Ireland, sends our emails, the sign-in codes among them.
• Stripe takes payment for an order.
• Lulu and BookVault print the books. The printer gets your book file, and the name, address, phone number and email address for the delivery.
• PostHog counts visits to this website, on its European servers.
• Netlify serves the pages of this website.
• Google Fonts sends this website its typefaces, and sees your device's internet address when it does.
• Pushover puts a chat message you send us on our phone, so we see it straight away.

Each company gets only what its job needs. We share your data with them for that job alone, and each of them protects it to the same standard as this page.

How long it is kept

Everything in your account is kept until you delete the account. Deleting it removes all of it straight away: your recordings, photographs, written lines, quotes and reminders, your settings, the journals you built and their photographs, where you came from, your email address and the account itself.

• An order you paid for is kept for six years, as tax law in Ireland requires, with your account taken off it. The print file of that book stays with the order so the printer can make it again.
• A chat or an email you send us is kept until you ask us to delete it.

What Astera does not do

• No ads on Astera, and nothing is sold or handed to an advertiser.
• No tracking across other websites, and no advertising pixel of any kind.
• Nobody reads your recordings or your pages to build a profile of you.
• Recordings are transcribed only if you ask for it, one recording at a time.

How visits are counted

Astera counts visits with PostHog, on their European servers. It runs cookieless, which means the visitor id is worked out at their end and nothing at all is written to your device. That is why this site has no cookie banner: there is no cookie to ask you about.

• What is counted on asterajournal.com: the first page you opened, where you came from, which journal you pressed, which question you opened, and whether you went through to the builder.
• What is counted in the builder at /app/: which screen you are on, whether the brief bar was used and whether it worked, and whether an order was started. Not what you write. Your pages, your answers and your photographs are never sent to PostHog.
• Screen recording is on for this brochure and off inside the builder, because the builder is where you write things that are yours.
• Your address is used to work out the town you are in and is then discarded rather than stored.

To keep your own visits out of it on this device, open asterajournal.com/?ph_optout=1 once. It holds until you clear site data, and it is per browser, so a phone needs its own tap.

Deleting your account and switching things off

• In the app, open Settings, then Account, then Delete account.
• By email, write to hello@spremtlabs.com from the address you sign in with and ask us to delete your account. We delete it within 30 days. How to delete your account has both.
• The app stops using your microphone, camera or photos when you turn them off for Astera in your phone's settings. What you already saved stays in your account until you delete it.
• The morning reminders stop when you turn off notifications for Astera in your phone's settings.
• The emails about an unfinished journal stop when you press the link at the bottom of any of them.

Asking a question

Write to hello@spremtlabs.com. Under the General Data Protection Regulation you can ask what is held about you, ask for it to be corrected, ask for it to be deleted, and complain to the Data Protection Commission in Ireland.
