Issue 04/Legal/Terms of Service

The terms we operate under.

ArbiBase is built for operators, so these terms read like one wrote them. No mystery clauses, no buried fees. Just the agreement between you, your account, and the platform.

Plain-English Summary
  1. 01
    We index, you operate.

    ArbiBase is a tool. We don't sign your lease, broker your deal, or manage your unit. You do.

  2. 02
    Verified ≠ guaranteed.

    Verification means consent + compliance was checked at a point in time. Frameworks change. Laws change. You confirm before you sign.

  3. 03
    Numbers are estimates.

    Underwriting outputs are based on data and operator-reported comps. They're directional. They are not financial advice.

  4. 04
    You own your data.

    Your unit data, comps, and notes belong to you. Cancel and you can export everything for 90 days.

  5. 05
    Pay monthly, cancel any time.

    No annual lock-in unless you ask for one. Cancellations stop renewal at the end of the current cycle.

  6. 06
    Disputes go to arbitration.

    Most disagreements are resolved by binding arbitration in Miami-Dade County, FL. You can opt out within 30 days of first signing up.

§ 01

Acceptance of these terms

By creating an ArbiBase account, accessing the platform, or otherwise using any of our services, you agree to be bound by these Terms of Service ("Terms"), our Privacy Policy, and any service-specific addenda we attach when you enable a feature.

If you're entering into these Terms on behalf of a company or other legal entity, you represent that you have authority to bind that entity. "You" then refers to both you personally and the entity. If you don't have that authority, or you don't agree with what's below, don't use the platform.

Effective date These Terms apply to all access on or after May 1, 2026. Continued use after a revision constitutes acceptance of the revised version. We'll always tell you when material changes ship.
§ 02

Definitions

Defined terms appear in bold on first use throughout these Terms. The most-used ones:

Platform
The ArbiBase web application, APIs, data feeds, and any related services we provide at arbibase.com.
Operator
You: the user signing leases and running short-term or mid-term rental units. The audience these Terms are written for.
Landlord
A property owner who has submitted a unit to our index. Landlords are not parties to these Terms with you.
Verified inventory
A unit that has cleared the four-step verification described in our methodology, current at the time it was last re-verified.
Underwriting outputs
Any pro-forma, occupancy estimate, ADR estimate, or cash-on-cash projection generated by our tools.
Operator data
Data you import or generate on the platform: your portfolio, comps you record, deals you underwrite, notes, exports.
§ 03

Account & eligibility

To open an account you must be at least 18 years old, legally capable of entering into a binding contract in your jurisdiction, and not barred from receiving the platform under U.S. or other applicable export controls or sanctions.

Account responsibility

  • You're responsible for everything that happens under your login. Pick a strong password and don't share it.
  • Notify us at security@arbibase.com within 24 hours of any unauthorized access.
  • One human, one account. Sharing seats across operators on different portfolios is a breach of these Terms.
  • We may verify your identity and operator status before unlocking certain features (deal exports, API access, bulk verification requests).
§ 04

Verified inventory & operator reliance

The verification process (landlord attestation, lease and rider review, HOA / building rules, city + state framework, 90-day re-verification) is described in our methodology. We follow it on every unit in the index. We say "no" to roughly one in four submissions.

Verification is a snapshot, not a guarantee. A unit verified today may stop qualifying tomorrow if the landlord revokes attestation, the building rules change, or the city framework moves. We re-verify every 15-30 days and flag affected listings within 24 hours of a known change. The law moves faster than any platform, and the final compliance check is yours.

Verification tiers

  • V1 - Verbal: Owner/manager expressed verbal openness to arbitrage/subleasing. A recording, transcript, or call log may exist.
  • V2 - Written: A written statement (email/text) indicates openness and any noted conditions.
  • V3 - Digital: A consent form is filled out by the owner explicitly permitting STR/MTR or subleasing under defined terms.

What we don't do

  • We don't broker your deal. We don't take landlord-side fees. We don't sign leases on your behalf.
  • We don't guarantee a landlord will accept your offer, sign a rider, or honor an attestation in a future dispute.
  • We don't guarantee continued legality of STR/MTR operation in any market. Frameworks change frequently.
Operator's check Landlords, HOAs, municipalities, and building managers may change positions at any time and may still deny applications based on screening (credit, background, income, availability, etc.). All verification signals are informational and not guarantees. Before signing any lease found through ArbiBase, you must obtain your own written permission and fully executed agreements.
§ 05

Underwriting tools & estimates

Our underwriting tools generate directional estimates based on data and operator-reported revenue, occupancy, and ADR data. They're meant to help you compare deals quickly, not to replace your own due diligence or the advice of a financial professional.

You acknowledge that:

  1. Underwriting outputs are estimates only and may differ materially from real-world performance.
  2. Comps reported by other operators are reported in good faith but not independently audited by ArbiBase.
  3. Future market conditions, regulatory changes, and your own operating decisions affect actual returns.
  4. Nothing on the platform constitutes financial, investment, tax, legal, or accounting advice.
§ 06

Subscription, billing & taxes

Plans & billing

Paid plans renew on a monthly cycle starting on the day you first subscribe. The fee for the upcoming cycle is charged at the start of that cycle. We'll email a receipt within 24 hours.

Cancellation

You may cancel at any time in the portal or by contacting billing@arbibase.com; cancellation takes effect at the end of the current term.

Refunds

  • Monthly plans: Refunds available only within 7 days of your first payment for new subscriptions.
  • Annual plans: Refundable within 30 days of first payment; non-refundable thereafter.
  • Except as described above or required by law, all fees are non-refundable and no credits are issued for partial periods.

Taxes

Fees are exclusive of sales, use, VAT, GST, or similar taxes. Where applicable, we'll add them at checkout and remit them to the relevant authority. You're responsible for any income, gross receipts, or franchise taxes assessed on your operating activity.

§ 07

Acceptable use

The platform is licensed for use by you and your team in operating your own portfolio. The following are prohibited and grounds for immediate termination without refund:

  • Reselling, sublicensing, or otherwise redistributing inventory data, comps, or underwriting outputs to third parties.
  • Scraping, crawling, or bulk-extracting any portion of the platform that isn't accessible through our public API.
  • Reverse-engineering the verification process, our scoring, or any non-public model used by the platform.
  • Submitting false comps, fabricated revenue numbers, or false attestations to inflate the index or deceive other operators.
  • Using the platform to facilitate any illegal STR/MTR operation in jurisdictions where it isn't permitted.
  • Probing, scanning, or testing the security of the platform without prior written permission from security@arbibase.com.
§ 08

Intellectual property

The platform, its source code, the verification methodology, the underwriting models, our brand marks, and the design of any data visualization on the platform are owned by ArbiBase, LLC and protected by U.S. and international intellectual property laws.

We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the platform during your active subscription, solely for the purpose of operating your own portfolio. No other rights are granted.

You retain ownership of your operator data (defined above). By submitting it to the platform, you grant us a license to host, process, back up, display to you, and aggregate it into anonymized comps for the benefit of all operators. Anonymized comp data, once aggregated, cannot be withdrawn; the underlying record stays attributable to you and is exportable.

§ 09

Operator data & privacy

How we collect, store, and process personal and operating data is governed by our Privacy Policy, which is incorporated into these Terms by reference. The short version:

  • Your portfolio, deals, notes, and exports are encrypted at rest and only visible to you and accounts you've explicitly invited.
  • We never sell operator data. We don't have a marketing data product.
  • Comp aggregation is anonymous and cell-suppressed below thresholds that could re-identify a single operator or unit.
  • You can export everything from Settings → Export at any time during, and for 90 days after, your subscription.
§ 10

Landlords, third parties & disputes

ArbiBase is not a party to your lease, your insurance policy, your management contract, or any other agreement you enter into based on inventory found through the platform. Disputes between you and a landlord, guest, agent, or any third party are between those parties.

If a verification turns out to be inaccurate at the time it was performed because of a process failure on our side, our liability is governed by § 13 (Limitation of liability) below.

§ 11

Termination & suspension

You can terminate your account at any time. We can terminate or suspend your account if you breach these Terms, abuse the platform, fail to pay, or use the platform in a way that creates legal risk for ArbiBase or other operators.

On termination: your access ends, scheduled renewals are canceled, and your data enters a 90-day export window. After 90 days, operator data is deleted from production systems within 30 days and from backups within an additional 90 days.

§ 12

Disclaimers

The platform is provided "as is" and "as available". To the maximum extent permitted by law, ArbiBase disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty arising out of course of dealing or trade usage.

We do not warrant that the platform will be uninterrupted, error-free, that defects will be corrected on any particular schedule, or that the platform or the servers we run it on are free of viruses or other harmful components.

§ 13

Limitation of liability

To the maximum extent permitted by law, in no event will ArbiBase, its officers, directors, employees, or agents be liable for any indirect, incidental, special, consequential, or punitive damages (including lost profits, lost revenue, lost data, or business interruption) arising out of or related to your use of the platform.

TO THE EXTENT PERMITTED BY LAW, ARBIBASE'S TOTAL AGGREGATE LIABILITY FOR ANY CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES WILL NOT EXCEED THE AMOUNTS PAID BY YOU TO ARBIBASE IN THE THREE (3) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM (OR US$500, WHICHEVER IS GREATER). Some jurisdictions do not allow certain limitations; some limits may not apply to you.

§ 14

Indemnification

You agree to defend, indemnify, and hold harmless ArbiBase and its officers, directors, employees, and agents from any claim, liability, loss, or expense (including reasonable attorneys' fees) arising out of: (a) your use of the platform in violation of these Terms, (b) any lease, deal, or operating activity you enter into based on platform inventory, or (c) any false or misleading information you submit to the platform.

§ 15

Arbitration & class waiver

Before filing any claim, the parties will attempt to resolve disputes informally for 30 days after written notice to the other party.

If not resolved, any dispute, claim, or controversy arising out of or relating to these Terms or the platform will be resolved by binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules (and, where applicable, the Consumer Rules). The arbitration will take place in Miami-Dade County, Florida, or by video/teleconference at the arbitrator's discretion. The arbitrator shall issue a written award and may award equitable relief when permitted by law.

You and ArbiBase agree to bring claims against each other only in your individual capacities, not as a plaintiff or class member in any class, collective, or representative action.

Either party may seek temporary or preliminary injunctive relief or pursue IP enforcement in a court of competent jurisdiction without first engaging in arbitration. Any claim must be filed within one (1) year after it accrued, except where a longer period is required by law.

30-day opt-out You may opt out of arbitration within 30 days of first accepting these Terms by sending written notice to legal@arbibase.com with the subject line "Arbitration Opt-Out" and your account details. If you opt out, the exclusive venue for disputes will be the courts specified in § 16.
§ 16

Governing law

These Terms are governed by the laws of the State of Florida, without regard to conflicts principles. Subject to arbitration above, the state and federal courts located in Miami-Dade County, Florida will have exclusive jurisdiction, and the parties consent to personal jurisdiction there.

If a court finds the class-action waiver unenforceable, the arbitration agreement is void as to that proceeding.

§ 17

Changes to these terms

We may revise these Terms from time to time. When we do, we'll update the Last revised date at the top, post a summary of what changed in the changelog below, and for material changes email every active account at least 14 days before the new version takes effect.

If you keep using the platform after a revision goes into effect, that's acceptance. If you don't agree, cancel before the effective date and the prior version governs your final cycle.

§ 18
