Privacy Policy

Last updated September 18, 2026

This Privacy Policy explains how Diachronic, Inc. ("Diachronic," "we," "us," or "our"), which operates the Rambi application and related websites (together, the "App"), collects, uses, discloses, and otherwise processes information. Rambi is a voice-response application: you answer prompts by speaking, and you accrue a cash balance. Payouts are available only while paid mode is on.

By creating an account or using the App, you acknowledge that you have read this Policy. Your use of the App is also governed by our Terms of Service, which are incorporated here by reference.

1. Information we collect

Account information. Your email address, the display name or username you choose, and authentication data.

Voice recordings. The audio you record when responding to prompts.

Transcripts and derived data. Text transcripts of your recordings, together with automated analyses generated from them, which may include topic and coverage information and quality and eligibility signals.

Activity and balance data. Your accrued balance, credit ledger, and the prompts you have viewed, answered, or dismissed.

Payment information. The email address on your account, which is where we send your reward if a payout is issued. We share your name and that email address with Giftogram, our payouts provider, only when a payout is actually being sent, and only so that they can deliver it. We do not receive or store your gift card codes, bank details, or card numbers.

Device and usage data. Technical and diagnostic information generated when you use the App, including device identifiers, app version, log data, and general usage patterns.

Website analytics. The tryrambi.com landing page records two anonymous events: that the page was loaded, and that a link to the Google Play listing was clicked. Each event carries the campaign parameters in the link you followed (for example, which email brought you), the domain that referred you, and nothing else. We do not place cookies and store nothing on your device for this, so these events are not linked to you, to each other across visits, or to your Rambi account. If your browser sends a Global Privacy Control or Do Not Track signal, the page records nothing at all.

Approximate location. We do not ask for location permission and the App does not read your device location. Our analytics provider derives an approximate location from the IP address your requests come from, which can indicate your city and time zone but not your exact position. You can turn this off with the analytics switch in Settings. We separately use the country your request comes from to decide which currency to show amounts in. That check is not stored, and turning off analytics does not disable it, because the App needs it to display prices correctly.

2. How we use information

We process the information described above in order to:

Where the GDPR or a similar law applies, our legal bases are as follows. We rely on performance of a contract with you to operate your account and process payouts; on our legitimate interests to secure the App, prevent fraud and abuse, and improve our services; and on compliance with legal obligations where applicable. We rely on your explicit consent for the sale, sharing, and licensing of your data to third parties, and for the processing of your voice recordings and the transcripts derived from them insofar as these constitute special category data under Article 9. You may withdraw that consent at any time by turning paid mode off, which stops the relevant processing going forward without affecting processing already carried out.

3. Voice recordings and biometric notice

Some jurisdictions treat voice data as biometric information. Where that is the case, this section serves as our written notice and, together with the acknowledgment you provide in the App, as your written release.

We collect and store audio recordings of your voice for the purposes described in Section 2, namely transcription, quality control, analysis, fraud prevention, and improvement of the App. We do not use your recordings to create a voiceprint for the purpose of identifying you. We run automated checks on your responses to detect fraud, duplicate accounts, and machine-generated submissions; these operate on transcript content and account signals rather than on the biometric characteristics of your voice.

Voice recordings are retained as described in Section 6. We will not disclose voice recordings except as described in Section 5, to service providers acting on our behalf under contract, or as required by law.

4. Service providers

We disclose information to vendors and service providers that perform functions on our behalf, under agreements that restrict their use of that information to providing services to us. These providers fall into the following categories:

A current list of our subprocessors is available to enterprise customers, research partners, and data protection authorities on request at contact@tryrambi.com.

We may also disclose information in connection with a merger, acquisition, financing, reorganization, sale of assets, or bankruptcy, in which case information about you may be transferred as a business asset. We may disclose information where we believe it is required by law, legal process, or governmental request, or where we believe disclosure is necessary to protect the rights, property, safety, or security of Diachronic, our users, or the public, or to investigate or prevent fraud or abuse.

5. Sale and sharing of personal information

Paid mode requires your affirmative opt-in and is off until you turn it on. While it is on, we sell and share the categories of data described in this section. You may turn it off at any time in Settings, and turning it off stops future sale and sharing.

While "Get paid for my answers" is on, you authorize Diachronic to sell, share, license, and otherwise disclose your responses and the data derived from them to third parties for their own commercial and research purposes. In exchange, you may accrue a cash balance on the terms described in our Terms of Service. We do not sell or share data we have identified as sensitive personal data belonging to residents of jurisdictions that prohibit such sale, including Maryland and New Jersey.

You may turn paid mode off at any time in Settings. Turning it off stops future sales, sharing, and licensing. It does not, and cannot, unwind disclosures already made, reverse licenses already granted, or require the return, deletion, or recall of data already provided to a recipient or already incorporated into a recipient's models, datasets, or products.

5A. Notice of financial incentive

Paid mode is a financial incentive program: you receive a cash balance in exchange for permitting the sale and sharing of your data. Participation requires your affirmative opt-in, and you may withdraw at any time in Settings.

Good-faith estimate of value. We estimate that the value of your personal information to us is approximately equal to the total amount we pay you for it. We calculate this by dividing the total amount we expend on participant payouts in a given period by the number of participants who accrued a balance in that period, which yields an estimate of approximately $10 per participant. This estimate reflects our cost of acquisition, does not reflect any resale price, and is not a representation of future value.

Non-discrimination. Declining paid mode, or withdrawing from it, does not affect your access to the App or your prompts. If you have never turned paid mode on, you continue to accrue a balance. If you turn paid mode on and later turn it off, accrual stops. Payouts are available only while paid mode is on.

6. Retention

Voice recordings. Retained for as long as necessary to fulfil the purposes described in this Policy, and in any event permanently destroyed when that purpose has been satisfied or within three years of your last interaction with the App, whichever occurs first. Requests concerning voice recordings are governed by Section 9 and are subject to the exceptions and limitations set out in this Policy and permitted by applicable law, including any legal or regulatory retention obligation and Section 7. Deletion of your account severs the association between you and your voice recordings; the recordings are retained in that unlinked form and are governed by Section 7. Copies may persist in backup and archival systems for a limited period after deletion.

De-identified transcripts and derived data. Scrubbed transcripts and the data derived from them are retained indefinitely, detached from your account and identity, and are used for the purposes described in this Policy. This data survives deletion of your account.

Account and activity data. Profile information, balances, and ledgers are retained while your account is active, and for a further period afterward as needed to comply with legal obligations, resolve disputes, prevent fraud, and enforce our agreements.

You may delete your account at any time through the App, or by submitting a request to contact@tryrambi.com. Account deletion removes your profile and the other data we hold that directly identifies you, and severs the link between you and your recordings and transcripts. It does not affect your unlinked recordings, de-identified transcripts and derived data, or data already disclosed to third parties.

7. De-identified and aggregated data

Data that has been de-identified or aggregated such that it is not reasonably capable of being associated with an identified or identifiable individual is not treated as personal information under this Policy. Pseudonymized data, meaning data that could still be attributed to you through the use of additional information held separately, remains personal data under the GDPR and UK GDPR and continues to be protected under this Policy for users to whom those laws apply. We may use, retain, license, sell, publish, and otherwise exploit such data for any lawful purpose, without restriction and without further notice to you, and we may do so indefinitely. We do not attempt to re-identify data that we have de-identified.

8. Security

We maintain administrative, technical, and organizational safeguards designed to protect information against unauthorized access, use, alteration, and disclosure, and we restrict access to authorized personnel and contracted service providers. No system of storage or transmission is completely secure, and we do not warrant or guarantee that information will remain secure or free from unauthorized access. You provide information to us at your own risk.

9. Your choices and rights

Within the App you can edit your name, username, and email address, turn paid mode on or off, and delete your account. You may also contact us at contact@tryrambi.com to request access to, correction of, or deletion of personal information we hold about you, subject to the exceptions and limitations described in this Policy and permitted by law. We may require verification of your identity before acting on a request, and we may decline requests that are unfounded, excessive, or repetitive.

United States state privacy rights. Depending on your state of residence, you may have the right to know what personal information we collect and disclose, to request deletion or correction, to opt out of the sale or sharing of personal information and of targeted advertising, to limit the use of sensitive personal information, and not to be discriminated against for exercising these rights. Under the California Consumer Privacy Act as amended, information we collect, including voice recordings and inferences drawn to create a profile about you, constitutes sensitive personal information. You may direct us to limit the use and disclosure of that information to the purposes permitted under that statute by writing to contact@tryrambi.com with the subject line "Limit the Use of My Sensitive Personal Information." Because participating in paid mode relies on uses beyond those permitted purposes, exercising this right will end your participation in paid mode.

Paid mode is our opt-in and opt-out mechanism for the sale and sharing of personal information. It is off until you turn it on. You can turn it off again at any time in Settings, and you may also submit a request by writing to contact@tryrambi.com with the subject line "Do Not Sell or Share My Personal Information." We honor recognized opt-out preference signals, including Global Privacy Control, transmitted by your browser or device where technically feasible. Note that if you opt out of sale and sharing, you will no longer accrue a balance, which is a difference in the value of the service you receive rather than discriminatory treatment.

GDPR and UK GDPR rights. If you are in the European Economic Area, the United Kingdom, or Switzerland, you may have the rights of access, rectification, erasure, restriction, portability, and objection, and the right to withdraw consent at any time without affecting processing carried out before withdrawal. You may lodge a complaint with your supervisory authority.

10. International transfers

We operate in the United States, and information we collect is processed and stored in the United States and in other countries where our service providers operate. These countries may have data protection laws that differ from those in your jurisdiction. Where required, we rely on appropriate transfer mechanisms, including the European Commission's Standard Contractual Clauses.

11. Children

The App is intended for adults. It is not directed to individuals under 18 years of age. We ask for your date of birth when you create an account and do not permit registration by anyone under 18. We do not knowingly collect personal information from individuals under 18, and if we learn that we have, we will delete the account, the associated identifying information, and the associated voice recordings.

12. Changes to this Policy

We may update this Policy at any time. Changes take effect when the updated Policy is posted, and the date at the top of this page will be revised. Where required by law, we will provide additional notice or obtain consent. Your continued use of the App after an update constitutes acceptance of the updated Policy.

13. Contact

Questions or requests may be sent to contact@tryrambi.com. Diachronic, Inc. is the controller of personal information processed through the App. See also our Terms of Service.
