Privacy Policy

This policy explains how we handle personal data when you use our service — in particular Live Call Translation, with which you make a phone call yourself, get help to answer in German from your own language and, once the other party has agreed, see a live translation of what they say on your screen. A separate notice for the people you call explains the same processing to them.

1. Who we are

This service is operated by TamerinTECH GmbH, Seestr. 19, 83727 Schliersee, Germany (email: [email protected]) — full company details are in the imprint. We are the controller responsible for the personal data described here.

2. What Live Call Translation does

You call a German business or organization from your browser and speak in your own voice. The call is carried by our telephone providers — not by your own phone plan — and shows a shared service number as caller ID, not your own number. A computer voice speaks on the line only if you tap a sentence for it, and only after the other party has agreed (see Section 4).

Before a call you can add a short note ("Anything I should know?") and photograph a letter the call is about (up to three pages) or paste its text; all of this is optional. The photo or text is sent to our approved AI model (Microsoft Azure OpenAI, EU Data Zone) only to read off the sender, the phone number, reference numbers (for example Aktenzeichen, Versicherungsnummer or Kundennummer), the subject line (Betreff), the date of the letter, a deadline, an amount and a short description in your language. The photo or pasted text itself is never stored — it is held in memory only for that one request. What was read becomes part of the call's preparation data only if you then start the call; you can remove it before.

Live help is optional and starts only with the other party's permission: at the start of the call you read a short notice to them yourself — that your German is not very good yet, whether you may use an automatic translation on your screen, and that nothing is recorded (on calls that offer a computer voice, also that a computer voice sometimes reads out for you) — and tap They agreed only after a clear yes. Until then no conversation audio is passed to speech-to-text or to any AI — the call runs as a normal phone call. With permission, the service shows what the other party says, translated into your language, at most one short suggestion and — when they ask for something that is on your letter — that detail. Throughout the call you can also write or say in your own language what you want to answer and get the German sentence and its pronunciation, which you read aloud yourself — or not; ready-made German phrases are also at hand. Once the other party has agreed, and on calls that offer it, you can instead tap Say it for me and a computer voice says the sentence you chose into the call. Details are in Section 4.

3. Data we process

• Account data: email address, display name, your own language (the one we translate into), app language and call preferences.
• Your replies: what you type or say in your own language to get the German sentence you want to read aloud — as text or, with Speak, as a short voice clip taken while your microphone is off the call. It is processed by Microsoft Azure OpenAI in the EU Data Zone and is not stored (see Section 4). If you tap Say it for me, only the German sentence you chose is sent, as text, to Azure OpenAI text-to-speech — during the pilot in the United States (Azure region East US 2, see Section 8) — so that a computer voice can say it into the call; the spoken sentence becomes part of the conversation text as your own turn.
• Records of your acceptances: which version of the Terms and the Acceptable Use Policy you accepted and when (at sign-up and with the declaration you confirm before a call), the purchase terms you accepted for a call time package and — recorded separately — whether you asked us to start the service immediately during the withdrawal period; each together with your IP address and browser identifier.
• Preparation data: the number and name of the business you want to call, your optional note and — if you photographed a letter or pasted its text and then started the call — what was read from it (sender, phone number, reference numbers, subject line, dates, deadline, amount and a short description); the photo or pasted text itself is not stored. Destination numbers are checked before a call is allowed (see Section 8).
• Call records: the number called, time and duration of the call, the type of destination (for example German landline or mobile), the connected seconds used, and technical events (dialing, answer, hang-up, connection quality) — no conversation content.
• Conversation content during live help — only after permission: the audio of the other party and your own audio as two separate live streams, the text recognized from them, translations and suggestions, and the sentences a computer voice said for you. This content is held only in our server's memory (see Section 4).
• A saved summary — only if you explicitly choose to save one after a call (off by default): a short AI-generated summary of the call, stored with the call in your account.
• Permission records: for every permission event (for example granted, refused, withdrawn, paused, resumed, new person on the line): call reference, time, sequence number of the permission, version and language of the notice, processing scope (for example whether a computer voice may be used), and the evidence method "user attestation" — never conversation content.
• Your own phone number, if you provide one: used for the SMS verification of your own number, so that you can test the service by calling yourself.
• Purchase and call time data: packages you buy, price and currency, order and payment status, Stripe references, invoices, the call time credited, reserved and used per call (in seconds), refunds, and withdrawal declarations you send us (name, email, contract reference, time of receipt). Card data is handled by Stripe; we never see full card numbers.
• Usage and cost figures per call: seconds of speech-to-text per channel and for dictated replies, number and size of AI requests, number, length (in characters) and duration of the sentences said by the computer voice, and response times — for cost accounting and quality, never content.
• Human-check data: at sign-in, a Cloudflare Turnstile check may process technical browser signals to tell humans from bots (see Section 8). We only receive and store the pass/fail outcome, never the signals.
• Technical data: server logs limited to technical events — no conversation content, no unmasked phone numbers. Usage statistics on our public pages (collected by us, no third party, IP address not stored): pages viewed, clicks, how far you scroll and how long the page is open and in use; on the early-access questions page also the answers you pick — even if you do not leave your email — a language you searched for that we do not offer, your device type, browser and operating-system family, screen size, browser language, the country our network provider derives from your connection, the referring website and the ad campaign and keyword that brought you. If you join the early-access list from that page, your visit is linked to your entry. Kept for up to 180 days.

4. Live help: permission first

• Nothing before permission. While live help is waiting for permission, the call audio is only transmitted between you and the other party to carry the call (including the short technical buffers a phone connection needs). It does not reach speech-to-text, translation or any AI, it is not recorded, and the computer voice cannot be used. What you type or dictate for your own replies is not call audio; it is covered by the last point of this section.
• Permission is your attestation. You read the notice aloud and tap They agreed only after a clear yes. We cannot verify the other party's answer ourselves: the tap is your confirmation to us, and we record it as exactly that (see the permission records in Section 3).
• Refusal: if the other party says no, the call continues as a normal phone call; no live help runs, but you can still get help with your own replies (without the conversation as context), which you then read out yourself — the computer voice is not used.
• Withdrawal: if the other party withdraws permission during the call, you tap the corresponding button. Processing stops immediately and the conversation text collected so far is discarded — no further captions, translations, suggestions or summaries are produced from it, it is no longer used as context for your replies, and the computer voice stops: a sentence that has not played yet is not spoken.
• New person on the line: if you are transferred or someone else joins, live help — including the computer voice — pauses until that person has agreed as well.
• Pausing: you can pause live help at any time; the speech-to-text streams are closed and the computer voice is unavailable while it is paused.
• Where the content goes: with permission, the two audio streams are sent to Microsoft Azure OpenAI speech-to-text to produce the live captions, and short text passages are sent, together with your preparation data, to an Azure OpenAI language model to produce translations and suggestions and to point out a detail from your letter when the other party asks for it; when you tap Say it for me, the German sentence you chose is sent as text to an Azure OpenAI text-to-speech deployment, which returns the audio played into the call. We have configured speech-to-text and the language model in the EU Data Zone (Azure region Sweden Central); during the pilot, the text-to-speech deployment runs in the United States (Azure region East US 2) and receives only the German sentence you chose (see Section 8). Only processors that we have explicitly approved for this purpose are used; if none is available, the app shows live help as unavailable instead of switching to another provider.
• How long it stays: we do not record or store the audio — neither the call's nor the computer voice's. The conversation text (including the sentences the computer voice said for you) is held only in server memory during the call and for a 10-minute review window after it, so that you can reread it, and is then deleted; you can close the review earlier. It is not written to our database, logs or analytics. What remains is the call record, the permission records and — only if you choose to save one — a summary.
• Your own replies, letters and the computer voice: what you type or say to get a German sentence is your own content, so this help works with or without the other party's permission. While you hold Speak, your microphone is taken off the call — the other party hears silence — and the short clip is sent to Azure OpenAI speech-to-text (EU Data Zone) and then discarded; it is never stored. Your words, together with your preparation data, go to the Azure OpenAI language model (EU Data Zone), which returns the German sentence and its pronunciation. The conversation so far is included as context only while the other party's permission is active. A letter photo or pasted letter text is read the same way before the call (Section 2) and is never stored. Say it for me works only on calls whose opener told the other party that a computer voice sometimes reads out for you, and only while their permission is active (checked again right before the sentence plays): the computer voice says exactly the sentence you tapped — your composed reply or a ready-made phrase — never anything on its own. Both sides hear it, and your microphone stays off the line while it plays.

5. What we deliberately do not do

• No audio recordings. Call audio is processed as a live stream — to carry your call and, with permission, to produce captions — and is never stored by us; neither are the voice clips of your dictated replies, the computer voice's audio, your letter photos or pasted letter texts.
• No conversation text in our database, logs or analytics for Live Call Translation calls — except a summary you explicitly save.
• No synthetic voice without your tap and their permission. Suggestions and the German sentences prepared for your replies are text for you to read; selecting one never plays audio. A computer voice says a sentence into the call only when you tap Say it for me for that sentence, only on calls whose opener announced it and only while the other party's permission is active — it never conducts the conversation and never says anything you did not choose.
• No AI training with your data or the other party's. We use our AI providers under agreements that exclude training on the data we send them.
• No call content, called numbers, preparation notes or letter details are passed to Stripe, to advertising partners or to our analytics.
• No cold calls or marketing calls. The service is technically limited to individual calls you make, each screened and individually confirmed by you.

6. Legal bases (GDPR)

• Performance of contract (Art. 6(1)(b)): your account, call preparation (including reading a letter you photograph or paste), carrying your calls, help with your own replies (including the computer voice for sentences you choose), live help as far as it concerns you and your own speech, purchases, call time accounting, and handling your withdrawal.
• Consent of the other party (Art. 6(1)(a)): processing the other party's speech for live help. You ask for this consent on the call before live help starts and confirm it to us; it can be refused without any effect on the call and withdrawn at any time with effect for the future.
• Legal obligations (Art. 6(1)(c)): keeping invoices and accounting records under German commercial and tax law, and confirming receipt of withdrawal declarations.
• Legitimate interests (Art. 6(1)(f)): being able to show that live help only ran with permission (permission records) and to prove your acceptances, abuse prevention and security (screening, destination check, human check, rate limits, suppression list), cost accounting without content, and short-lived technical logs. This also covers understanding and improving our public pages with our own usage statistics (Section 3).
• Your consent (Art. 6(1)(a)) for marketing cookies and optional notifications; you can withdraw it at any time.
• Your consent (Art. 6(1)(a)) for the Germany pilot's early-access list (waiting list): we store your email address, when and to which wording you consented, the promised 10 free call minutes and — if you signed up on our questions page — your three answers (the language you want help in, what is hardest about German phone calls, how often you call) and, if you came from an ad, the campaign and keyword. The answers only help us decide which languages and features to open first. Only if you accepted marketing cookies do we also store the ad click identifier and, after you confirm your email, report that click to Google Ads (Google Ireland Ltd.) as a conversion — never your email address or your answers. We write to you once, when you can try the pilot. You can withdraw at any time with the link in our confirmation email (“Remove my email from the list”) or via [email protected].

7. Information for the people you call

People called through the service can read a dedicated notice for people you call. In short:

• They speak with a person — our user. A computer voice says only sentences our user taps, only if the notice announced it and only after they agreed; it never conducts the conversation. The call shows a shared service number, not the user's own number.
• They are asked before live help starts, can refuse without any consequence for the call, and can withdraw their permission at any time.
• No audio is recorded. The conversation text exists only temporarily in server memory — during the call and for up to 10 minutes afterwards — unless our user saves a short summary of the call.
• If they ask not to receive calls made through the service — during the call or by contacting us — their number goes on a suppression list and will not be called again by any user. The list stores only the number and the request; keeping it is what honors the objection, so it survives even the requesting user's account deletion.
• They can exercise their GDPR rights (access, erasure, objection) at [email protected] and may complain to a supervisory authority.

8. Processors and recipients

• Hosting: OVHcloud (data centers in Germany/the EU).
• Telephony: our telephone providers carry the call and, in transit, its audio and call data (numbers, times) — Twilio and/or Vonage, or a SIP telephone provider connected to our own telephony server; EU routing where available. The same providers deliver the SMS for verifying your own number.
• Live help, call preparation and your replies: Microsoft (Azure OpenAI Service) — speech-to-text (also for replies you dictate) and a language model (which also reads the letter photos you take or letter texts you paste and turns your replies into German), deployed in the EU Data Zone (Azure region Sweden Central), and text-to-speech for Say it for me, which receives only the German sentence you chose, as text — never call audio. During the pilot phase only, text-to-speech runs in the United States (Azure region East US 2, US Data Zone). Microsoft processes the data on our behalf and does not use it to train models; any temporary storage on Microsoft's side (for example for abuse monitoring) is governed by Microsoft's data processing terms.
• Earlier offer only (Section 11): Microsoft Azure OpenAI and/or OpenAI (live transcription, text-to-speech of typed sentences, short text processing) and ElevenLabs (text-to-speech of typed sentences — it receives only typed text, never call audio).
• Destination check: Google (Places directory lookup of the business number you enter — the number, never your identity).
• Payments: Stripe (hosted checkout, payment processing, invoices).
• Email: Cloudflare Email Service (sign-in links, purchase and withdrawal confirmations, notifications). Push notifications: your browser's push service.
• Network, TLS and bot protection: Cloudflare (including the Turnstile human check at sign-in).

Where a provider or its sub-processors operate outside the EU/EEA, transfers rely on adequacy decisions (including the EU-US Data Privacy Framework) or Standard Contractual Clauses; this includes the pilot text-to-speech for Say it for me in the United States (Microsoft, Azure region East US 2), which receives only the German sentence you chose. Apart from this pilot exception, we choose EU processing options wherever the provider offers them.

9. Retention

• Call audio, voice clips of dictated replies, the computer voice's audio, letter photos and pasted letter texts: not stored by us.
• Conversation text of Live Call Translation calls: in server memory only; deleted at the latest 10 minutes after the call ends (earlier if you close the review), and immediately when permission is withdrawn.
• Saved summaries: until you delete them or your account.
• Permission records: kept with your account and deleted when you delete your account.
• Call records and call history (preparation data such as your note and what was read from a letter, call times and duration): until you delete them or your account.
• Technical call events: deleted after 30 days.
• Usage and cost figures (no content): while your account exists.
• Acceptance records: while your account exists, deleted with it — except where they document a purchase and must be kept like billing records.
• Orders, invoices, call time ledger and withdrawal declarations: for the periods required by German commercial and tax law (billing records are also kept by Stripe).
• Account: until you delete it.
• Early-access list (waiting list): until you withdraw or we have sent your invitation; entries that were never confirmed are deleted after 30 days, and removing your email also deletes your answers and any conversion not yet reported.
• Encrypted database backups age out after 14 days.
• Suppression list (opt-out numbers): kept until the number's holder asks us to remove it — it exists to honor the opt-out.

10. Your rights and the tools for them

• Export: download all your data as JSON in Settings → "Your data".
• Erasure: delete your account and all its data in Settings, delete a saved summary at any time, and — for the earlier offer — delete call transcripts ahead of their automatic deletion.
• You additionally have the rights to access, rectify, restrict and port your data, to object to processing based on legitimate interests, and to withdraw consent with effect for the future: [email protected].
• You may lodge a complaint with a supervisory authority; in Germany this is the data-protection authority of your federal state.

11. Earlier offer: assisted calls with credits

Accounts that use our earlier assisted-calling offer (paid with credits) are handled as before for those calls, for as long as we provide that offer:

• Live captions of the other side are produced from the call audio from the start of the call. The legal basis is our legitimate interest (Art. 6(1)(f)) in enabling live assistance on a call you make yourself.
• Sentences you type can be spoken on the call by a synthetic voice, exactly as typed; the text-to-speech provider receives only your typed text, never call audio.
• A temporary text transcript of the conversation is stored encrypted and deleted automatically within at most 7 days; the structured result (for example an appointment time) stays in your history.
• A callback number you entered for a call is given to the business only if you chose that for the call.

12. Changes

We will announce material changes to this policy in the app before they take effect.

13. Users in the United States

We are a German company: your data is processed as described above, on servers in the European Union (during the pilot, except the text-to-speech for Say it for me — see Section 8), with the GDPR as our baseline for everyone — wherever you are. If you are a US resident, the following applies in addition:

• We do not sell your personal information, and we do not share it for cross-context behavioral advertising (as those terms are defined in the California Consumer Privacy Act and similar state laws).
• State privacy laws (such as the CCPA/CPRA in California) may give you rights to know, access, correct, delete, and port your personal information, and to opt out of sale or sharing. The tools in Section 10 (export, deletion) serve those rights too; for anything else, write to [email protected]. We do not discriminate against you for exercising your rights.
• We process your data only for the purposes in this policy; the retention rules in Section 9 apply unchanged.
• Where state law provides for it, an authorized agent may submit a request on your behalf; we will verify the request before acting on it.
