HavnOS is a record, not a professional opinion
This is the important one. HavnOS organises what your documents say and reminds you about maintenance. It is not an inspector, an engineer, a contractor, a lawyer, an accountant or an insurer, and nothing it shows you is professional advice.
Two specific cases where this matters: anything involving gas, electricity, structure or water intrusion should be looked at by a licensed professional, whatever we say about it. And tax categories — capital improvement versus repair — are our reading of your documents, to be checked by your accountant before you file.
Documents get read imperfectly
We extract dates, amounts and obligations from paperwork, and sometimes we get one wrong. That is why every extraction shows the sentence and page it came from. The document is the authority; our reading of it is a convenience. Check anything you are going to rely on, particularly a deadline with money attached.
Your account
You are responsible for what happens under your login, so use a real password and turn on two-factor. Tell us at security@havnos.com if you think someone else has access.
Your content stays yours
Your documents and records belong to you. You grant us only the permission needed to store them, read them at your request, and show them back to you. We claim no ownership and take no rights to use them for anything else.
Paying
Paid plans bill monthly or annually until cancelled. Cancel any time; access continues to the end of the period you have paid for. Cancelling does not delete your record — you move to the free plan.
AI document reads are metered per plan. Multiple properties are part of the Max+ plan, which includes 3 properties; each property after that is a flat $25 a month, with no change at any number.
Renewal. Plans renew automatically at the end of each period — monthly on the same day each month, annual on the same date each year — at the price then published, until you cancel. We will tell you before any price change affects you.
Refunds. Every paid plan carries a 30-day money-back guarantee from your first payment: ask within 30 days and we refund it in full, no reason needed. After that, cancelling stops the next payment and you keep access to the end of the period you have already paid for. We do not pro-rate a refund for time unused in a period, except where the law where you live says otherwise — in which case the law wins.
Changing plan mid-term. Moving up takes effect immediately and we charge the difference for the days remaining, not a full period. Moving down credits the unused difference against your next invoice rather than paying it out. Adding or removing a property works the same way.
If a payment fails. We retry over about two weeks and email you each time. Your record is not touched while that runs. If it never succeeds the subscription ends and you move to the free plan — you keep every document, and nothing is deleted for non-payment.
Deleting your account. You can delete it yourself from Account, and doing so cancels any subscription immediately. The remainder of a period already paid for is not refunded, so if you are inside the 30-day guarantee, ask for the refund first.
Affiliates
Affiliates earn 25% of what people they refer actually pay, for as long as those people keep paying — not for a fixed term — and at whatever plan they are on, moving with them if they upgrade. Self-referral does not count, and referrals must be people who genuinely wanted the product. Details on the affiliates page.
Changes to the service
We add to and change the service over time. Where something is incomplete or uncertain we say so on the screen where it happens, not in a clause down here. If a change removes something you pay for, we tell you before it takes effect and you can cancel with the rest of the term refunded.
Ending it
You can close your account at any time. We may suspend an account that is being used to attack the service or harm other people; if we do, you can still get your data out.
