The short version. Your conversations live only in your browser, on your device. We keep no copy of them on any server, we cannot read them, and they are never used to train any AI. If you pay for Senda, we hold what billing requires, your email address and subscription status, and nothing more. Your conversations are never connected to your payment details.
Your conversations. What you write (or dictate) is sent from your browser to our server functions and on to our AI providers for one purpose only: composing each reply. Nothing of your conversation content is stored or logged on our servers; it exists there only for the seconds a reply takes. Your conversation history is saved solely in your own browser. Because you may choose to share personal, emotional, or health-related things in a conversation, we treat all conversation content as if it were sensitive: processed transiently for the reply you asked for, on the basis of your explicit choice to write it, and never retained, profiled, or analysed by us.
Voice dictation. If you use the microphone, your audio clip is sent to a transcription provider, converted to text, and returned. The audio is used for that transcription only and is not kept by us.
Billing (paying members). Payments are handled by Stripe. Stripe holds your name, email, and payment details as an independent payment processor. We can see your email address and the status of your subscription, which we keep in order to provide your access. Legal basis: performance of our contract with you, and legal obligations (accounting).
Transcripts you choose to send. Senda has a button to send a transcript to Andrés to help improve the product. This happens only when you press it. Transcripts you send are kept confidentially, read for product improvement, and deleted on request. Legal basis: your consent, which you can withdraw at any time.
What stays on your device. Conversation history, continuity notes, your Path material, and the name you may set in Settings are stored in your browser only. The AI never sees your name. Clearing your browser's site data deletes this material permanently; we hold no copy and cannot restore it.
Some of these providers process data outside the EU. Where they do, transfers rest on recognised safeguards such as the EU-US Data Privacy Framework or standard contractual clauses.
No analytics, no tracking, no advertising, no cookies beyond what the app strictly needs to function, no selling or sharing of your data, and no use of your words to train AI models. We built Senda this way on purpose.
Billing records are kept as long as accounting law requires. Transcripts you sent are kept while useful for improving Senda, or until you ask us to delete them. Everything else lives on your device, under your control.
Under the GDPR you can ask us for access to, correction of, or deletion of the personal data we hold about you (which, in most cases, is your email and subscription status, plus any transcript you sent). You can also object to or restrict processing, ask for portability, and withdraw consent at any time. Write to andres@folkuslab.com and we will respond promptly. You also have the right to complain to a supervisory authority; in Finland this is the Office of the Data Protection Ombudsman (tietosuoja.fi).
If this policy changes in any way that matters, we will tell you in the app before the change takes effect, in plain language.
