Silvivia — Privacy Policy

Last updated: 19 October 2026 · Operated by Solonava Labs, LLC

1. Who we are

Silvivia is a single-user life-admin companion operated at silvivia.com by Solonava Labs, LLC, a California limited liability company based in the United States. References to "we", "us", "our", or "Silvivia" in this policy mean Solonava Labs, LLC. You can reach us at support@silvivia.com. This policy explains what personal data we collect about you, how we use it, and the choices you have.

2. Data you give us

Account: name, email address, password (hashed), phone number (optional).
Phone notifications: if you allow notifications in the Silvivia iPhone app, a push token that identifies the app on your phone, so we can send you reminders. It is removed when you delete the app, delete your account, or choose to stop reminders when signing out of the app on that phone; if someone else signs in on that phone, it moves to their account.
Content you enter: tasks, appointments, contacts, notes, medication entries, document uploads, "I'm OK" check-ins.
Document photos and files: when you add a document in the iPhone app, the phone itself reads the photo or PDF (using Apple's on-device text recognition) to suggest the kind of document, its expiry date and whose it is. The picture is not sent to us or to any AI service for this. The files you choose to keep are stored privately so you can view them later (see Cloudflare below). You can also import a contact from your iPhone's contacts; only the contact you pick is copied, and only when you pick it.
Billing: handled by Stripe on the website or Apple through the App Store in the iPhone app. We do not store your full card details on our servers, only the customer, subscriber and subscription identifiers needed to manage access.

3. Data we collect automatically

Standard server logs (IP address, browser, request paths, timestamps) used for security, abuse prevention and debugging. Session cookies / bearer tokens used to keep you logged in.

4. How we use your data

To provide the Silvivia service to you and only you (single-user app).
To send transactional emails (trial warning on day 28, account / billing notices).
To process and verify subscriptions through Stripe or Apple.
To keep the service secure and operating reliably.

We do not sell your personal data, and we do not use your content for advertising.

5. Sub-processors

Stripe — payment processing.
Apple — App Store subscription payment processing for the iPhone app, Sign in with Apple if you choose to use it, and delivery of phone notifications to your iPhone.
RevenueCat — manages and verifies App Store subscriptions for the iPhone app. It receives your account identifier and subscription status, not your card details.
Google — Sign in with Google if you choose to use it, and the web fonts used on the website (your browser loads them from Google's font servers, which can see your IP address).
Resend — transactional email delivery.
Twilio, Inc. — SMS, WhatsApp and voice message delivery.
OpenAI — powers the "Tell Silvivia" AI assistant. When you use the assistant, your conversation text and a snapshot of the relevant items in your account are sent to generate the reply: for example task and appointment names and times, medication names, your saved documents' names, kinds, owners, expiry dates and reminders, and your contacts' names, categories, phone numbers and email addresses. Pictures of your documents and anything printed on them (such as document numbers) are never sent. We do not use your conversations to train AI models.
ElevenLabs — turns the assistant's replies, memos and tutorial narration into spoken audio when you use the read-aloud features. The text being read is sent for this sole purpose.
Expo — relays phone notifications from the Silvivia iPhone app to Apple. It receives your phone's push token and the notification text, which includes the reminder's details (for example “Time to call George”) unless you choose Hide details in the app's notification settings, in which case it is a generic message (“You have a reminder from Silvivia”).
Open-Meteo — provides weather forecasts when you ask the assistant about the weather. Only the place name you mention is sent.
Railway — application hosting and the PostgreSQL database.
Cloudflare — domain name service and storage of the files you upload to Documents.

6. Retention & deletion

If you do not start a paid subscription within the 30-day free trial (or if a paid subscription later lapses without renewal), your account is paused and your data is retained for 60 days. Subscribing within that window fully restores your account and data. If 60 days pass without a paid subscription, your account and all associated data are then permanently deleted. You can also delete your account at any time from Settings; deletion is permanent and removes all your stored content (subject to short-lived backups required for disaster recovery, normally cleared within 30 days).

7. Your rights

Depending on where you live (e.g. GDPR / UK GDPR / CCPA), you have the right to access, correct, export or delete your personal data, and to object to certain processing. Contact us at privacy@silvivia.com to exercise these rights.

8. Security & data breaches

Passwords are hashed with bcrypt. Traffic is served over HTTPS. We follow common industry practices to keep your data safe, but no online service is 100% secure. Please use a strong, unique password and do not share your login credentials with anyone. You acknowledge that, despite our efforts, data breaches, unauthorised access, hacking, interception or accidental disclosure may occur — whether on our systems, on a sub-processor's systems (Stripe, Resend, Twilio, Railway, Cloudflare), or in transit. To the maximum extent permitted by law, Solonava Labs, LLC accepts no liability for any loss or damage arising from such events, from incorrect or unintended use of the app, or from undetected bugs or errors in the service (see also the Limitation of Liability section of our Terms of Service). If a breach affecting your personal data does occur, we will notify you and any relevant regulator as required by applicable law.

9. Children

Silvivia is not intended for children under 16. Do not create an account if you are under that age.

Silvivia can deliver reminders for tasks, appointments and medications by email, SMS text message, WhatsApp message and automated voice call, depending on the channels you turn on in Settings.

How we collect your number. You provide your mobile phone number yourself in Settings and tick the box(es) for the channels you want to receive (SMS, WhatsApp, voice). Phone collection is always opt-in and you can change or remove your number at any time. See how SMS opt-in works.
What we send. Only transactional reminders that you have scheduled in your own account (e.g. "Your appointment with Dr Smith is in 30 minutes"). We do not send marketing or promotional messages over SMS, WhatsApp or voice.
Frequency. Message frequency varies and depends entirely on the reminders you create — typically a few messages per day, but you control it.
Opting out. Reply STOP to any SMS to immediately unsubscribe from all SMS reminders; reply HELP for help. For WhatsApp, reply STOP or remove WhatsApp in Settings. For voice, you can disable voice calls in Settings at any time.
Carrier costs. Standard message and data rates may apply to SMS and voice messages, depending on your mobile plan and carrier.
No third-party sharing. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging originator opt-in data and consent will not be shared with any third parties. Your phone number and the contents of your reminders are only passed to our messaging sub-processor Twilio, Inc. for the sole purpose of delivering the messages you asked for.
Carrier disclaimer. Mobile carriers are not liable for delayed or undelivered messages.
