Privacy promise
Plain-language privacy. The lawyer version is over here.
This page explains how we actually think about your data - and the data of the people you store in Spark. It is not the legal privacy policy. It is the human one, written so you can read it once and know what you're signing up for.
The product is the subscription. Not your data.
Spark makes money one way: people pay a monthly or annual subscription for the app. That's it. We do not sell your contact list. We do not sell aggregated "insights" about your network. We do not license your data to AI training partners. We do not run ads.
The day we change any of that is the day the company has lost its reason to exist, and we know it.
Integrations are optional. Your broader communications stay yours.
Spark does not require broad inbox, calendar, or message access to be useful. You can import contacts explicitly, tell Spark what matters, and keep using the product without connecting a communications account.
If Spark later offers email or calendar integrations, they will be opt-in, scoped to the feature you turn on, and never used for model training. We will not quietly scan everything you have ever written and call that "intelligence."
You choose exactly which contacts to import. Nothing syncs in the background.
Importing uses your phone's Contacts permission - and inside Spark, you choose exactly which people to bring in. Skip someone and they never touch our servers.
We never sync your address book in the background, and we never re-read it except when you start an import. The permission exists to power the import you asked for - not to quietly mirror your phone.
Voice is for the conversation. Not for keeping.
When you hold the mic to dictate to Spark, your speech is transcribed using your phone's speech recognition when available - the only thing our server receives is the same text you saw on your screen.
Full voice mode - a live, back-and-forth conversation with Spark - works differently: your audio streams to our speech provider to power the conversation in real time. It's processed to run that conversation, not stored as recordings, and never used for training.
Other people's data is treated with the same care.
The people you store in Spark didn't sign up to be mined as data. They're in your contact list because they know you - that's the contract. So we're careful with their data the same way we're careful with yours: nothing leaves Spark except in service of features you've explicitly turned on, and nothing gets sold.
When you delete a contact, all the notes, dates, and AI-distilled facts about them are deleted with them. Including from our backups, within 30 days.
AI calls are routed through providers we vet, not stored beyond what's needed.
Spark uses third-party AI providers - currently Claude from Anthropic for drafting messages, refreshing contact bios, and the morning curation job, and OpenAI for live voice conversations. We have data processing agreements with our providers. They do not train models on your data. We do not retain raw prompt/response pairs beyond what's needed to debug a specific issue.
For Pro users, news grounding works by deduplicating topics across all Pro users into a single global search per topic - so if 200 people in Spark follow the Ravens, there's one Ravens search per day, not 200. Your contacts and your topics are never sent to the news API. Only the topic string.
You can export everything. Any time.
Me → Account → Export my data downloads a JSON export of the user-owned records Spark stores for you: account profile, contacts, notes, interactions, reminders, tags, import history, legal acceptances, feedback, AI conversations, relationships, and organizations. The export is yours to keep whether or not you stay a customer.
If you cancel and delete your account, Spark sends an email confirmation first. Once confirmed, your account data is deleted or anonymized according to the legal privacy policy. We do not keep a shadow copy "just in case."
AI activity is logged, visible, and correctable.
We don't think you should have to trust an AI assistant on faith. AI activity - generated suggestions, context questions, bio refreshes, and notes Spark added - appears in Me → History → AI activity. When Spark makes a concrete change for you inside Spark Chat, the action card includes Undo, so bad filings are correctable without hiding the audit trail.
Privacy isn't a feature. It's the precondition for a relationship app being worth using at all. If we ever drift from any of the above, we expect - and want - our users to call us on it.
