Welcome to Arca. These Terms of Service are the agreement between you and Arcaneas LLC ("Arcaneas", "we", "us"), the California company that makes Arca. By creating a family account or using Arca, you agree to these Terms and to our Privacy Notice.
At a glance: Arca is $4.99 a month or $39.99 a year (US dollars, plus any applicable tax). Every new family starts with a 14-day free trial, no card needed, and we send you a reminder email before it ends. When you choose a plan, it starts that day and renews automatically, so your family's routines keep running without interruption. You can manage your plan at any time in the app (☰ → Settings → Subscription → Manage subscription) or by emailing arca@arcaneas.com.
1. Who Arca is for
Arca is built for families. A parent or legal guardian who is at least 18 years old and lives in the United States creates and manages the family account. Children enjoy Arca through the profile their parent sets up for them, on a device the parent has signed in; all account and billing decisions stay with the parent.
2. Your family account
- You look after your family's account, including keeping your email and parent PIN private.
- You're welcome to invite another parent or guardian to share your family; everyone you invite agrees to these Terms when they join.
- Keeping your information accurate helps Arca work well for you. If you ever think someone else has accessed your account, email arca@arcaneas.com and we'll help right away.
3. Plans and pricing
- Monthly: $4.99, billed each month.
- Yearly: $39.99, billed once a year (about 4 months free compared with monthly).
- Founding Family offer: our first 10 paying families may be offered the yearly plan at $29.99 for their first year, after which it continues at the regular yearly price.
- One plan covers your whole family: every parent and every child in your family account.
- Prices are in US dollars, with sales tax added where required by law.
- If our pricing ever changes, we'll let you know by email at least 30 days before the new price applies to your plan.
4. Your free trial
- Every new family gets 14 days of Arca free, with full access to every feature. No payment card is needed to start.
- You can choose a monthly or yearly plan at any time during or after your trial. Your plan, and your first payment, start on the day you choose it.
- We'll email you friendly reminders a few days before your trial ends and the day before.
- If no plan is chosen when the trial ends, your family's Arca moves to view-only mode as described in section 8. Nothing is ever charged without you choosing a plan.
- The free trial is available once per family.
5. Automatic renewal
Your plan renews automatically at the end of each month or year, using your card on file at the current price, so your family never loses access. We email you a receipt after every payment. By choosing a plan, you authorize these recurring payments.
6. Managing your plan
- You're always in control. In the app, go to ☰ → Settings → Subscription → Manage subscription to switch plans, update your card, view receipts, or stop renewal. It takes just a few taps, and you can also reach us at arca@arcaneas.com.
- If you stop renewal, Arca stays fully available until the end of the period you've paid for.
- Your family's information stays safe in your account until you choose to delete it (☰ → Settings → Delete family account).
7. Refunds
- Monthly plan: each month is billed on its own, and stopping renewal takes effect from your next billing date. Partial months aren't refunded.
- Yearly plan: you're covered by our 14-day guarantee. Ask within 14 days of any yearly payment (your first or a renewal) for a full refund of that payment.
- If anything ever looks wrong with a charge, such as a duplicate payment, email arca@arcaneas.com and we'll make it right promptly.
- Refunds go back to your original card and usually appear within 5–10 business days.
8. Keeping your account active
If your free trial ends without a plan, or a payment doesn't go through, we'll let you know so you can choose a plan or update your card. In the meantime your family's Arca stays available in view-only mode: everyone can still see checklists and the calendar, and everything comes back to full use as soon as a plan is active. Your family's information is kept safe for 30 days, and we'll always email you before anything is removed, so you have time to reactivate or request a copy of your information.
9. Tester codes
From time to time we invite families to help us test Arca with a tester code, which gives that family free access for the period we share with them. Each tester code is personal to one family and isn't transferable. Tester families don't need to add a payment card. When the tester period ends, the family can continue on a regular monthly or yearly plan; until then, section 8 applies.
10. Using Arca respectfully
Arca is for your own family's personal use, in line with the law. To keep Arca safe for every family, please respect other families' privacy, the security of the service, and our work: no attempts to access other accounts, disrupt the service, copy or resell the app, or use it to harm anyone. We may suspend an account that puts other families or the service at risk; if we ever close a paid account for a reason that isn't your fault, we'll refund the unused part of your plan.
11. Your family's information
Everything you add to Arca (your kids' names, checklists, calendar and more) belongs to you. You allow us to store and process it only to run Arca for your family, as described in our Privacy Notice. We never sell it, and Arca never shows ads.
12. Voice and AI features
Arca's voice and AI helpers, such as Ask Arca and Scan a flyer, are designed to save you time. Because speech and documents can occasionally be misread, Arca always shows you what it understood before saving, so you can confirm dates, times and names. Arca is a family organizer and is not intended as a safety, medical or emergency service.
13. Updates to Arca and to these Terms
We're always improving Arca, so features will grow and change over time. If we make an important change to these Terms, we'll let you know by email or in the app before it takes effect. Continuing to use Arca after that date means you accept the updated Terms.
14. Our commitment and its limits
We work hard to keep Arca available, reliable and secure. Like any online service, Arca is provided "as is" and "as available", and we can't guarantee it will always be uninterrupted or error-free. To the extent the law allows, Arcaneas is not liable for indirect or consequential losses, and our total liability for any claim relating to Arca is limited to the amount you paid us in the 12 months before the claim. Nothing in these Terms limits any rights you have under consumer protection laws that can't be waived.
15. If Arca ever changes course
Your family account remains yours to keep or delete whenever you choose. If we ever decide to stop offering Arca, we'll give you at least 30 days' notice, the opportunity to request a copy of your information, and a refund of any unused prepaid time.
16. Governing law
These Terms are governed by the laws of the State of California. Any dispute will be handled in the state or federal courts located in Santa Clara County, California, unless the law where you live gives you the right to bring it elsewhere. We'd always like the chance to help first, so please email us with any concern; most questions are resolved quickly.
