These Terms of Service (“Terms”) cover your access to and use of Dudum. Using the app means you agree to them. If you don’t agree, please don’t use Dudum.
1. The product, in one paragraph
Dudum lets you write letters to your future self, pick a delivery date, seal them, and read them when the day arrives. Some features need a one-time Platinum purchase. Everything else is free.
2. Your account
You sign in with Apple or Google. The verified email address your identity provider returns becomes your delivery address. Keeping access to that identity provider is on you. If you lose access to your Apple or Google account, we can’t recover your Dudum account for you.
You must be at least 13 years old, or the minimum age required where you live, to use Dudum.
3. Your letters
The letters you write belong to you. You grant Dudum a limited license to store, transmit, and deliver them, only so we can run the service.
Once a letter is sealed (either manually, or automatically after the seven-day edit window), it can’t be read, edited, or deleted one by one. This is intentional. The sealed state is a core part of the product.
4. Platinum
Platinum is a one-time purchase. It isn’t a subscription. There’s no trial and no recurring charge. The price you paid is the price you paid. If we raise the price for new users later, that doesn’t affect you.
Purchases are handled by Apple or Google. Refund requests go through the store where you bought Platinum, under their refund policy.
If you buy Platinum on one platform (say, iOS), it follows you when you sign in on another (say, Android) with the same account.
5. Delivery
Dudum commits to best-effort delivery of every letter on its chosen date. On that day, we send an email to your registered address and a push notification to your device (if you’ve enabled them). The letter becomes readable inside the app the same day.
Keeping your identity provider’s email working is on you. If your email address goes stale (for example, by revoking Apple’s private email relay, or abandoning the inbox), email delivery may fail. The letter itself still lives inside the app, waiting for you whenever you sign in.
6. Service continuity
Our intent is to keep Dudum running for a long time. If we ever have to shut it down, we commit to:
- Giving you at least 90 days of notice.
- Sending any sealed, undelivered letters to your registered email address before we shut down.
Beyond that commitment, Dudum is provided “as is” and without any warranty. We do our best to deliver reliably, but we can’t guarantee uninterrupted service.
7. Acceptable use
You agree not to use Dudum to:
- Upload content that’s illegal where you live.
- Gain, or try to gain, unauthorized access to the service or to other users’ data.
- Interfere with how the service runs, including by scraping, reverse-engineering, or sending automated traffic.
We reserve the right to suspend or close accounts that violate these Terms, particularly where content is illegal or where activity harms our ability to run the service.
8. Deleting your account
You can delete your Dudum account from the app at any time. Deletion is permanent. Every letter goes with it, including sealed letters that haven’t been delivered yet, and they can’t be recovered. There’s no user-facing way to export letters from the app. The sealed state is core to the product, so the only way letters leave Dudum in bulk is the shutdown archive described above.
9. Changes to the service
We may change, add, or remove features of Dudum over time. We’ll do our best to preserve the core letter-writing experience for as long as the service exists.
10. Limitation of liability
To the extent permitted by applicable law, Dudum and Star48 aren’t liable for any indirect, incidental, consequential, or special damages arising from your use of the service. Our total liability to you for any claim relating to Dudum is limited to what you’ve paid us in the twelve months before the claim arose, or, if you’re on the free plan, USD $25.
11. Governing law
These Terms are governed by the laws of France, without regard to conflict-of-laws principles. If you live in a country whose laws give you rights that can’t be waived by contract, those rights still apply to you.
12. Changes to these terms
If we make meaningful changes, we’ll update the date at the top of the page and let you know inside the app before anything takes effect. Continuing to use Dudum after a change means you accept the updated Terms.
