Transom is an operations log for people who manage their own rental property: somewhere to record what happened at a unit, what it cost, and who did the work; to keep a list of what still needs doing; and to get the log back out again at tax time. It is a well-kept ledger with some arithmetic attached.
By creating an account or using the service you agree to these terms. If you do not agree, do not use Transom.
The tax export, the Schedule E categories, the mileage valuation, and the profitability views are conveniences built from what you logged. They are not tax advice, and nothing in Transom is a substitute for an accountant or an attorney.
That applies with particular force to mortgages. If you add a property’s loan terms, Transom works out the payment schedule from them — an estimate, not a statement from your lender, and one that will not match a recast, a rate change, extra principal, or escrow. It is deliberately kept out of the tax export for that reason: mortgage interest may be deductible, but the figure that belongs in a filing is the one on your lender’s Form 1098.
Return figures are arithmetic on what you typed, nothing more. A cash-on-cash return covers a period we can see, is scaled up to a year when you have owned the place for less than one — a projection, and labelled as such — and counts only the units whose purchase you have recorded. Transom knows what a property cost you. It does not know what it is worth and does not estimate it.
Where a figure depends on what a property is worth — equity, appreciation, return on equity — that value is one you entered. Transom does not appraise property, has no market data, and applies no judgement to the number you give it beyond refusing the impossible. Those figures are therefore your own estimate carried through arithmetic, and the responsibility for them is yours: they are not a valuation, not an appraisal, and not suitable for a lender, an insurer, a tax filing or a sale. If a figure matters, have it valued properly.
You are responsible for what you file. Check the numbers before they go anywhere: totals are only as good as the entries behind them, the mileage rate applied is the published standard rate in effect on the entry’s date (the IRS can and does change it mid-year), and a category we guessed is still a category you chose to accept. If a figure matters, verify it.
You need an account to use Transom. You can sign in with a Google account, an Apple account, or an email address and password. Give an address you actually control, keep your password to yourself, and tell us if you think someone else is in your account. You are responsible for what happens under it.
One account, one log: your log belongs to you alone, and no one else can read it. The one exception is the tenant portal in §5 — and a tenant you invite gets their own account and sees only their own requests, never your log. You can delete your account from Settings at any time, which erases everything filed under it.
You must be at least 18 years old to use this service — Transom is a tool for adults managing rental property. That applies to tenant accounts too.
There is a free plan and a paid one. The free plan covers one property (archived units don’t count — archiving one frees the slot) with every kind of log entry, photos and receipts, your to-dos, the nudges and reminders, the contractor directory, the assistant, the money pages and your deduction totals — with no time limit. It is not a trial. Transom Pro adds every further property you own and the CSV tax export itself, at the prices shown on the upgrade page, charged in advance.
Payments are handled by Stripe; we never see or store your card. You can cancel at any time from Settings, which opens Stripe’s billing portal: your subscription then runs to the end of the period you have already paid for and does not renew. We do not refund partial periods. If a payment fails, we keep your account on Pro while Stripe retries rather than locking you out.
Ending a subscription never deletes anything. Your account drops back to the free plan, every entry, to-do and photo stays exactly where it is, and any properties beyond the free plan’s one remain readable — and exportable again if you subscribe later. Archiving a property doesn’t delete it either: its log is kept and still appears in Money and in the tax export for any year it has entries. Restoring one puts it back in the plan’s count, so on the free plan it needs the slot to be free. If prices change, the change will be announced before it takes effect, and it will not reach back and lock up a log you already built.
Your log is yours. You grant Transom only the permission it needs to store your entries and show them back to you. We do not claim ownership of your records and we do not use them to train anything.
Entries are append-only: you can add to the log, and you can void a line you got wrong — voiding strikes it out so it stops counting in your totals and in the export, and you can restore it — but nothing edits or erases an entry in place, because the log is a financial record. To-dos are the exception — they are a working list, so you can edit or delete one whenever you like, and deleting one leaves anything you logged about it untouched. Export gives you a copy of the log whenever you want one, and deleting your account removes the lot.
When you use the assistant — the chat screen, or voice — the parts of your log relevant to your question are sent to an AI provider to produce the answer. The same provider drafts the suggested replies offered on a tenant work request that is waiting on you; those drafts only ever fill the message box, and nothing reaches your tenant until you send it yourself. Anything you send is your message, whether you typed it or edited a draft. Section 4 of the Privacy Policy says exactly which provider and exactly what is sent.
Your entries will often name a contractor and may describe a tenant. You decide what to record, and you are responsible for handling it lawfully — including any local rules about tenant records. Don’t put anything in the log you have no right to hold.
The tenant portal. You can invite someone to a property you own by entering their email address. Transom emails them the invitation link and also shows it to you, so you can pass it on yourself. Anyone holding that link can claim the tenancy, so enter the address carefully and send the link only to the person you meant to invite — treat it like a key. When they accept, they get their own account and a portal in which they can do exactly two things: file a work request against that property, and exchange messages with you on it. They cannot see your log, your money, your to-dos, your other properties or your other tenants. You can end their access from the property page at any time.
A work request is a message, not a promise. Transom records what was asked and what you said about it — it does not decide what repairs you owe, how fast you must act, or whether you have met any obligation. Those come from your lease and from your local law, and nothing in the app changes them. A request filed here does not constitute legal notice to anyone, and the portal is not monitored and must never be used to report an emergency — for anything urgent or unsafe, use the phone.
If you are a tenant here. Your account, your requests and your messages are yours; deleting your account removes them along with your name and email. The requests you filed stay on your landlord’s property record with no account attached, because that repair history is theirs.
You agree not to:
Transom is provided “as is” and is in active development. It may be unavailable, may change, and may lose recently entered data during an outage. Export anything you cannot afford to lose — especially before a filing deadline.
To the extent the law allows, we are not liable for indirect or consequential loss arising from your use of the app, including any tax or financial consequence of a figure you took from it. Nothing here limits liability that cannot lawfully be limited.
You may delete your account at any time from Settings → Delete account. Deletion is immediate and permanent, and we cannot restore your data afterwards.
We reserve the right to suspend or terminate accounts that violate these terms. Upon termination, your data will be deleted in accordance with our Privacy Policy.
These terms change as the app does; the “Last updated” date above moves when they do, material changes are announced in What’s New, and continued use after a change constitutes acceptance.
